Question

X^2 + 10x = 0
How do I solve for a completed square ?

Answer 1

x = 0 x = -10

Explanation:

First, use the AC method to figure out, what times what equals 0 and what adds up to equal 10, which would be 0 and 10.

Third, you would set each one equal to 0

x + 10 = 0 x + 0 = 0

Solve from there to get your two x's

x = 0 and x = -10

Answer 2

12x=0

Explanation:

x=0 because it is
