To solve the equation x^2 + 20 = 4 using square roots, we need to isolate x on one side of the equation.
First, we subtract 20 from both sides of the equation:
x^2 + 20 - 20 = 4 - 20
x^2 = -16
Next, we take the square root of both sides of the equation:
√(x^2) = √(-16)
Since the square root of a negative number is not a real number, there are no solutions to this equation.
Solve the equation using square roots.
x^2+ 20 = 4
