expand (a+7)/((a-1)(a-2)(a+1))

expand

\frac{a + 7}{( a - 1 ) ( a - 2 ) ( a + 1 )}

\frac{a + 7}{a ^{3} - 2 a ^{2} - a + 2}

Solution steps

\frac{a + 7}{( a - 1 ) ( a - 2 ) ( a + 1 )}

Expand

(a - 1) (a - 2) (a + 1) : a^{3} - 2 a^{2} - a + 2

= \frac{a + 7}{a ^{3} - 2 a ^{2} - a + 2}

\frac{- 3}{4} (- 16 v + 4 = - 111)

\frac{w ^{- 4}}{z ^{- 9}}

\frac{( 2 x - 1 ) ( 3 x + 5 )}{2}
