simplify (2a+2)/(a^2-1)

Solution

simplify

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

Solution

\frac{2}{a - 1}

Solution steps

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

Factor

2 a + 2 : 2 (a + 1)

= \frac{2 ( a + 1 )}{a ^{2} - 1}

Factor

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

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

Cancel the common factor:

a + 1

= \frac{2}{a - 1}
