To solve the equation 2x^2 - 20 = 0, we can follow these steps:
Step 1: Move the constant term to the other side of the equation.
Adding 20 to both sides of the equation gives us:
2x^2 = 20
Step 2: Divide both sides of the equation by the coefficient of x^2 to isolate x^2.
Dividing both sides by 2 yields:
x^2 = 10
Step 3: Take the square root of both sides of the equation to solve for x.
Taking the square root of both sides gives us:
x = ±√10
So the solutions to the equation 2x^2 - 20 = 0 are x = √10 and x = -√10.
