Answer 2

To solve the equation 2x² = 18, we need to isolate the variable x. Here's how you can do it step by step:

1. Divide both sides of the equation by 2 to get x² alone: (2x²) / 2 = 18 / 2 x² = 9

2. Take the square root of both sides to eliminate the exponent 2: √(x²) = √9 x = ±3

So the solutions to the equation 2x² = 18 are x = 3 and x = -3.
