Question

The steps to derive the quadratic formula are shown below:

Answer 1

Answer:

A. a times the quantity x squared plus b over a times x end quantity equals negative c

Step-by-step explanation:

ax^2 + bx + c = 0

Subtract c from each side

ax^2 + bx+c-c =0 − c

ax^2 + bx = − c

Now we factor out an a

a(x^2 +b/a) = -c

Answer 2

Answer:

A. a times the quantity x squared plus b over a times x end quantity equals negative c

Step-by-step explanation:

Step 1 ax² + bx + c = 0

Step 2 ax² + bx = − c

Step 3 a(x² + (b/a)x) = -c
