factor x-x^{b-1}

Solution

factor

x - x^{b - 1}

Solution

\frac{x ^{2} - x ^{b}}{x}

Solution steps

x - x^{b - 1}

Apply exponent rule:

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

= x - x^{- 1} x^{b}

Apply exponent rule:

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

x = x^{- 1} x^{2}

= x^{- 1} x^{2} - (x^{- 1} x^{2})^{b} (x^{- 1} x^{2})^{- 1}

Factor out common term

x^{- 1}

= x^{- 1} (x^{2} - x^{b})

Refine

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