Solve 4|x 1| |2x 1|=8

Evaluate

4 ∣ x \times 1 ∣ ∣ 2 x \times 1 ∣ = 8

Simplify

More Steps

8 x^{2} = 8

Divide both sides

\frac{8 x ^{2}}{8} = \frac{8}{8}

Divide the numbers

x^{2} = \frac{8}{8}

Divide the numbers

More Steps

x^{2} = 1

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

x = \pm 1

Simplify the expression

x = \pm 1

Separate the equation into 2 possible cases

x = 1 x = - 1

Solution

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

Solve the equation
