simplify 9/(2x^3)+(-2)/(2x^3)

simplify

\frac{9}{2 x ^{3}} + \frac{- 2}{2 x ^{3}}

\frac{7}{2 x ^{3}}

Solution steps

\frac{9}{2 x ^{3}} + \frac{- 2}{2 x ^{3}}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

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

= \frac{9}{2 x ^{3}} - \frac{2}{2 x ^{3}}
