Follow the process of completing the square to solve 2x2 + 8x - 12 = 0. After adding B2 to both sides of the equation in step 4, what is the constant on the right side of the equation? - 32 112 160 which one

Step-by-step explanation:

I dont quite understand the problem but this is one way to solve it using completing the square:-

2x^2 + 8x - 12 = 0

2 (x^2 + 4x) - 12 = 0

2 ((x + 2) ^2 - 4) = 12

2 (x + 2) ^2 - 8 + 8 = 12 + 8

2 (x + 2) ^2 = 20
