solve each of the following equations by the square root method and show your work
4x²-20=0
To solve the equation 4x² - 20 = 0 using the square root method, you can follow these steps:
Step 1: Move the constant term to the opposite side:
4x² = 20
Step 2: Divide both sides of the equation by the coefficient of x² to isolate x²:
x² = 20/4
x² = 5
Step 3: Take the square root of both sides:
√(x²) = √5
x = ±√5
Therefore, the solutions to the equation 4x² - 20 = 0 are x = √5 and x = -√5.
