Solve p(x) = -3x^3 - 2x^2 x

Evaluate

p (x) = - 3 x^{3} - 2 x^{2} \times x

Simplify

More Steps

p (x) = - 5 x^{3}

In the equation for p (x),replace p (x) with y

y = - 5 x^{3}

Interchange x and y

x = - 5 y^{3}

Swap the sides of the equation

- 5 y^{3} = x

Change the signs on both sides of the equation

5 y^{3} = - x

Divide both sides

\frac{5 y ^{3}}{5} = \frac{- x}{5}

Divide the numbers

y^{3} = \frac{- x}{5}

Use \frac{- a}{b} = \frac{a}{- b} = - \frac{a}{b} to rewrite the fraction

y^{3} = - \frac{x}{5}

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

3 y^{3} = 3 - \frac{x}{5}

Calculate

y = 3 - \frac{x}{5}

Simplify the root

y = - \frac{3 25 x}{5}

Solution

p^{- 1} (x) = - \frac{3 25 x}{5}
