Solve x^(2) 4x-64=0

Evaluate

x^{2} \times 4 x - 64 = 0

Multiply

More Steps

4 x^{3} - 64 = 0

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

4 x^{3} = 0 + 64

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

4 x^{3} = 64

Divide both sides

\frac{4 x ^{3}}{4} = \frac{64}{4}

Divide the numbers

x^{3} = \frac{64}{4}

Divide the numbers

More Steps

x^{3} = 16

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

3 x^{3} = 316

Calculate

x = 316
