PLEASE ANSWER Select the correct answer.

Caroline rewrote a quadratic equation in vertex form by completing the square, but her work has errors.

Identify the first error in her work.

A.

She incorrectly factored out the value of a.

B.

She subtracted the wrong value to maintain balance after completing the square.

C.

She incorrectly combined the constant terms.

D.

She squared the wrong value when completing the square.

She incorrectly factored out the value of a.

Step-by-step explanation:

In solving a quadratic equation by completing the square method, the value a is not factored out. Rather, the steps involved are:

Divide through all the terms by a

Move the term c/a to the right had side

Complete the square on both sides using the value of b/2

Obtain the values of x

y=mx+b

step-by-step explanation:

m slope, b y-intercept

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
