- 9 x - \frac{5 x}{7}

- \frac{68 x}{7}

Solution steps

- 9 x - \frac{5 x}{7}

Apply the fraction rule:

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

= \frac{- 9 x \cdot 7 - 5 x}{7}

Multiply the numbers:

= - \frac{68 x}{7}

(- i)^{- 5}

(x^{2} + 9 x + 7) (3 x^{2} + 9 x + 5)

\frac{x}{2 x - 6} + \frac{x - 2}{x + 1}

3 (- 3 - x^{2})
