Solve 12d 9d^2=-4

Evaluate

12 d \times 9 d^{2} = - 4

Multiply

More Steps

108 d^{3} = - 4

Divide both sides

\frac{108 d ^{3}}{108} = \frac{- 4}{108}

Divide the numbers

d^{3} = \frac{- 4}{108}

Divide the numbers

More Steps

d^{3} = - \frac{1}{27}

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

3 d^{3} = 3 - \frac{1}{27}

Calculate

d = 3 - \frac{1}{27}

Solution

More Steps

d = - \frac{1}{3}

Alternative Form

d = - 0. \dot{3}
