Solve x^2 8x-5=0 - ScanMath

Evaluate

x^{2} \times 8 x - 5 = 0

Multiply

More Steps

8 x^{3} - 5 = 0

Move the constant to the right-hand side and change its sign

8 x^{3} = 0 + 5

Removing 0 doesn't change the value,so remove it from the expression

8 x^{3} = 5

Divide both sides

\frac{8 x ^{3}}{8} = \frac{5}{8}

Divide the numbers

x^{3} = \frac{5}{8}

Take the 3 -th root on both sides of the equation

3 x^{3} = 3 \frac{5}{8}

Calculate

x = 3 \frac{5}{8}

Solution
