factor (a^2-1)/(a^2+2a-3)

factor

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

\frac{a + 1}{a + 3}

Solution steps

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

Factor

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

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

Factor

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

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

Cancel the common factor:

a - 1

= \frac{a + 1}{a + 3}

3 [4 x + 7 (2 - 2 x)]

4 x^{2} = 5 x + 21

- \frac{x}{( 16 + x ^{2} ) ^{\frac{3}{2}}}

ln (3) - ln (1)

\frac{2 x}{5} - \frac{x}{3} > 12 - \frac{x}{2}
