Yes.
If you post your work, someone will be glad to check it for you.
To solve the given equation 2x^2 - 20 = 0, we need to follow these steps:
Step 1: Move the constant term to the right side of the equation.
2x^2 = 20
Step 2: Divide both sides of the equation by the coefficient of x^2 to isolate x^2.
2x^2/2 = 20/2
x^2 = 10
Step 3: Take the square root of both sides of the equation.
√(x^2) = ±√10
x = ±√10
Therefore, the solution to the equation 2x^2 - 20 = 0 is x = ±√10.
