The Quadratic Function Y = 1 2 X2 − 5 2 X + 2, With Roots X = 1 And X = 4.

2 B C ⎜ ⎛ + X ⎟ ⎞ = − ⎝ 2 A ⎠.

When to use the quadratic formula. X2 + b ax + c a = 0 x 2 + b a x + c a = 0. View our text lesson on how to use.

Derivation Of The Quadratic Formula We Can Get A General Formula For The Solutions To By Doing Completing The Square On The General Equation.

X2 + b ax + b2 4a2 = b2 4a2 − c a. 2 b c 2 b ⎟ ⎞ x. That formula looks like magic, but you can follow.

First, We Bring The Equation To The Form Ax²+Bx+C=0, Where A, B, And C Are Coefficients.

To find the values of x (roots or zeros) where the parabola crosses. The quadratic formula helps us solve any quadratic equation.
