The four methods of solving a quadratic equation are Factoring, Completing the square, Quadratic formula, Graphing.

A quadratic equation is a type of polynomial equation that can be written in the form of ax^2 + bx + c = 0, where x is the variable, and a, b, and c are constants. The degree of the equation is 2, and it creates a parabolic shape when graphed. The solutions of a quadratic equation are also known as roots, and there can be zero, one or two distinct solutions. The solutions can be real or complex numbers. The most common method to find the roots of quadratic equation is using the quadratic formula: x = (-b ± √(b^2 - 4ac)) / 2a

The four 4 methods of solving quadratic equation are :

Factoring: This method involves factoring the quadratic equation into the product of two binomials. Once factored, you can set each binomial equal to zero and solve for the roots (x-values) of the equation.

Completing the square: This method involves rearranging the equation into a perfect square trinomial and then solving for the roots. The basic idea is to add and subtract the square of half the coefficient of the x^2 term to both sides of the equation.

Quadratic formula: This method utilizes the quadratic formula to find the roots of the equation. The formula is: x = (-b ± √(b^2 - 4ac)) / 2a

Graphing: This method involves plotting the equation on a coordinate plane and finding the x-values (roots) of the equation by observing where the graph intersects the x-axis.

All four method are used to find the x-intercepts(root) of the quadratic equation, which is the main goal of solving the quadratic equation.

4c=-4

c=-4/4

c=-1

Answer:

I. x = -4 and II. x = 12

Step-by-step explanation:

For this problem, you would simply need to plug in the values and see if the inequality is true, and if it is, it is a solution, so let's go through the options.

Plugging in x = -4 gives us: -4 < 12 which is true since negative four is less than positive twelve, so this is a solution.

Plugging in x = 0 gives us: 0 < 12 which is true since zero is less than twelve, so this is a solution.

Plugging in x = 12 gives us: 12 < 12 which is false since twelve is not less than twelve but is rather equal to it. if the less than symbol had a line under it, it would also include values equal to it in which case x = 12 would be a solution but since it doesn't, this is not a solution.

Plugging in x = 13 gives us: 13 < 12 which is false since thirteen is not less than twelve but is rather greater than it, so this is not a solution.

Any alternative for the variable in a function that results in a zero answer is said to as the zero of a function.

The x-intercept(s) of the function's graph, or the real zero of a function, is where the function's graph hits the x-axis graphically.

The values of the variable in a function that allow the function to equal zero are termed the zeros of the function. The places on the x-axis where the graph crosses the x-axis are referred to as a function's zeros graphically. In other respects, we can say that the zeros of something like a function are the x-intercepts of the graph.

Finding the values of the variable that correspond to the function's zeros can be achieved by equating the function to 0. By calculating the polynomial and then equating it to 0, we can discover the zeros for polynomials.

The equation, Y = - 2x + 3 has infinitely many solutions.

Here we are given the equation y = 2x + 3. Now since this equation has 2 variables, it can be easily plotted on a graph. After plotting this equation, we can see that it makes a never-ending line, hence, this equation will have infinitely many solutions.

For any equation to have a solution, there must be an intersecting point or a common value for x or y.

Here for every value of x, we get a different value of y, which can be easily seen in the graph.

Furthermore, when an equation has 2 variables, there must be at least 2 equations for the system to have a unique solution, hence the given equation has infinitely many solutions.

The shrink-wrapped carton of 64 juice boxes contained 2 gallons of juice.

To find out how many gallons of juice were in the shrink-wrapped carton, we first need to convert the number of juice boxes to cups and then convert that amount to gallons.

Each juice box contains 1/2 cup of juice, so 64 boxes contain 64 * (1/2) = 32 cups.

There are 16 cups in 1 gallon, so to convert 32 cups to gallons, we divide 32 cups by 16 cups/gallon.

32 cups / 16 cups/gallon = 2 gallons

So, the shrink-wrapped carton of 64 juice boxes contained 2 gallons of juice.

The given equation are:

2x + y = 5.........(1)

3x - 2y = 4.........(2)

Multiply equation 1 by 2 then add by equation 2.

The length of the unknown side of this right angled triangle is 12cm.

This is a question about the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. The theorem can be written as c^2 = a^2 + b^2, where c is the hypotenuse, and a and b are the other two sides.

In this case, we know that the base of the triangle is 8cm and the length is 9cm.

So we can use the formula c = √(a^2 + b^2)

c = √(8^2 + 9^2)

c = √(64 + 81)

c = √(145)

c = 12cm

These functions are defined in terms of the ratios of the sides of a right triangle. For example, the sine of an angle in a right triangle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.

In the given figure, we can apply the trigonometric ratio, we get
