expand ((a+1)(a-1))/(3(a+5))

expand

\frac{( a + 1 ) ( a - 1 )}{3 ( a + 5 )}

\frac{a ^{2} - 1}{3 a + 15}

Solution steps

\frac{( a + 1 ) ( a - 1 )}{3 ( a + 5 )}

Expand

3 (a + 5) : 3 a + 15

= \frac{( a + 1 ) ( a - 1 )}{3 a + 15}

Expand

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

= \frac{a ^{2} - 1}{3 a + 15}
