Solve for x: 2 (x + 3) 2 - 4 = 0

x=-2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2 (x+3) (2) - 4=0

4x+12+-4=0 (Distribute)

(4x) + (12+-4) = 0 (Combine Like Terms)

4x+8=0

4x+8=0

Step 2: Subtract 8 from both sides.

4x+8-8=0-8

4x=-8

Step 3: Divide both sides by 4.

4x/4 = -8/4

x=-2
