Question

What is the quadratic formula?

Answer 1

It is x = (-b ± √(b2 − 4ac))/(2a)

Plug the numbers from the quadratic equation into this formula. You can also solve using square root or completing the square which is ax^{2}+bx+c

Answer 2

Standard Form: y = a x 2 + b x + c y=ax^2+bx+c y=ax2+bx+c.

Factored Form: y = a ( x − r 1 ) ( x − r 2 ) y=a(x-r_1)(x-r_2) y=a(x−r1)(x−r2)

Vertex Form: y = a ( x − h ) 2 + k y=a(x-h)^2+k y=a(x−h)2+k.
