Solve w^2 4w-2=0 - ScanMath

Evaluate

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

Multiply

More Steps

4 w^{3} - 2 = 0

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

4 w^{3} = 0 + 2

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

4 w^{3} = 2

Divide both sides

\frac{4 w ^{3}}{4} = \frac{2}{4}

Divide the numbers

w^{3} = \frac{2}{4}

Cancel out the common factor 2

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

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

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

Calculate

w = 3 \frac{1}{2}

Solution
