Solve (-7)/9 z^2/5 z

Evaluate

\frac{- 7}{9} \times \frac{z ^{2}}{5} z

To find the roots of the expression,set the expression equal to 0

\frac{- 7}{9} \times \frac{z ^{2}}{5} z = 0

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

- \frac{7}{9} \times \frac{z ^{2}}{5} z = 0

Multiply the terms

More Steps

- \frac{7 z ^{3}}{45} = 0

Simplify

- 7 z^{3} = 0

Change the signs on both sides of the equation

7 z^{3} = 0

Rewrite the expression

z^{3} = 0

Solution

z = 0
