Question

Solve for x: 2(x + 3)2 − 4 = 0

Answer 1

x=-2

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
