What is the quadratic equation of 8 and 9?

The standard quadratic equation using the given set of solutions {8,−9} is y=x2+x−72 y = x 2 + x – 72 .

How does the quadratic formula work?

The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) . See examples of using the formula to solve a variety of equations.

What are the 8 quadratic equations?

A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term.

How do you find the square root of a quadratic equation?

For a quadratic equation ax2 + bx + c = 0, The roots are calculated using the formula, x = (-b ± √ (b² – 4ac) )/2a. Discriminant is, D = b2 – 4ac.

What does ax2 represent?

The term ax2 is called the quadratic term (hence the name given to the function), the term bx is called the linear term, and the term c is called the constant term. Quadratic functions are very good for describing the position of particles under constant (or near constant) acceleration.

Why do we use the quadratic formula?

In real life, the quadratic formula helps us in determining the area of space, the speed of a moving object, the value of profit gained on a product, and more. Even the path of a space rocket is described in terms of a quadratic equation.
