Polly · Answer 1

Steps to solve:

2x² = 8

~Divide 2 to both sides

2x²/2 = 8/2

~Simplify

x² = 4

~Take the square root of both sides

±√x² = ±√4

~Simplify

x = 2 or x = - 2

Best of Luck!

Dangelo · Answer 2

x = ±2

Step-by-step explanation:

2x^2 = 8

Divide each side by 2

2x^2/2 = 8/2

x^2 = 4

Take the square root of each side

sqrt (x^2) = ±sqrt (4)

x = ±2
