factor 7x^{-5}+4x^{-3}+2x^3

factor

7 x^{- 5} + 4 x^{- 3} + 2 x^{3}

\frac{7 + 4 x ^{2} + 2 x ^{8}}{x ^{5}}

Solution steps

7 x^{- 5} + 4 x^{- 3} + 2 x^{3}

Apply exponent rule:

a^{b + c} = a^{b} a^{c}

x^{- 3} = x^{- 5} x^{2}, x^{3} = x^{- 5} x^{8}

= 7 x^{- 5} + 4 x^{- 5} x^{2} + 2 x^{- 5} x^{8}

Factor out common term

x^{- 5}

= x^{- 5} (7 + 4 x^{2} + 2 x^{8})

Refine

= \frac{2 x ^{8} + 4 x ^{2} + 7}{x ^{5}}
