Tori Cunningham · Answer 1

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

Brooke Dennis · Answer 2

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
