Question

Follow the process of completing the square to solve 2x2 + 8x - 12 = 0.

Answer 1

Answer:

constant = -12

Step-by-step explanation:

Let the given equation be

2x² + 8x - 12 = 0     --------(1)

Here B² =(2√2)^2 = 8

Add 8 in both sides  of (1)

Step1 :  2x² + 8x  + 4 = 12  + 4

Step 2:  x² + 4x + 4 = 16

step 3 : x² + 4x + 4 - 16 = 0

Step 4:  x² + 4x - 12 = 0  ---(4)

From the (4) we get constant = -12
