Solve each equation by factoring x^2+4x+4=0

Answer: x = - 2

Step-by-step explanation:

Find 2 numbers whose product is the c-value of 4 and their sum is the b-value of 4.

x² + 4x + 4 = 0

∧

1 + 4 = 5

2 + 2 = 4 this works! so the factors are:

(x + 2) (x + 2) = 0

x + 2 = 0 and x + 2 = 0

x = - 2 and x = - 2 - -> same answer so only need to list it once
