Solve -10x^4 = -126

Evaluate

- 10 x^{4} = - 126

Change the signs on both sides of the equation

10 x^{4} = 126

Divide both sides

\frac{10 x ^{4}}{10} = \frac{126}{10}

Divide the numbers

x^{4} = \frac{126}{10}

Cancel out the common factor 2

x^{4} = \frac{63}{5}

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

x = \pm 4 \frac{63}{5}
