Question

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

Answer 1

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
