Solve 2x^2 x - 1 = 0

Evaluate

2 x^{2} \times x - 1 = 0

Multiply

More Steps

2 x^{3} - 1 = 0

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

2 x^{3} = 0 + 1

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

2 x^{3} = 1

Divide both sides

\frac{2 x ^{3}}{2} = \frac{1}{2}

Divide the numbers

x^{3} = \frac{1}{2}

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

3 x^{3} = 3 \frac{1}{2}

Calculate

x = 3 \frac{1}{2}
