Type your math problem... |x^2|=4

x

Question

Solve the equation

x_{1} = - 2, x_{2} = 2

Evaluate

x^{2} = 4

When the expression in absolute value bars is not negative, remove the bars

x^{2} = 4

Take the root of both sides of the equation and remember to use both positive and negative roots

x = \pm 4

Simplify the expression

More Steps

Evaluate

4

Write the number in exponential form with the base of 2
