Follow the process of completing the square to solve 2x^2 + 8x - 12 = 0. after adding b^2 to both sides of the equation in step 4, what is the constant on the right side of the equation?
1. -32
2. 112
3. 160

For this case we have the following equation

To complete squares we follow the steps below:

We divide between 2 on both sides of the equation:

We divide the term by 2 and square it. We add this to both sides of the equation:

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:
