Solve x^2 4x - 4 = 0

Evaluate

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

Multiply

More Steps

4 x^{3} - 4 = 0

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

4 x^{3} = 0 + 4

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

4 x^{3} = 4

Divide both sides

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

Divide the numbers

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

Divide the numbers

More Steps

x^{3} = 1

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

3 x^{3} = 31

Calculate

x = 31

Solution

x = 1
