Solve -2(-x 1) 2x-4=34

Evaluate

- 2 (- x \times 1) \times 2 x - 4 = 34

Rewrite the expression

- 2 (- x) \times 1 \times 2 x - 4 = 34

Multiply the terms

More Steps

4 x^{2} - 4 = 34

Add or subtract both sides

4 x^{2} = 38

Divide both sides

\frac{4 x ^{2}}{4} = \frac{38}{4}

Divide the numbers

x^{2} = \frac{19}{2}

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

x = \pm \frac{19}{2}

Simplify the expression

x = \pm \frac{38}{2}

Separate the equation into 2 possible cases

x = \frac{38}{2} x = - \frac{38}{2}

Solution

x_{1} = - \frac{38}{2}, x_{2} = \frac{38}{2}

Alternative Form

x_{1} \approx - 3.082207, x_{2} \approx 3.082207
