factor (x^2-1)/(x^2-9)

factor

\frac{x ^{2} - 1}{x ^{2} - 9}

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

Solution steps

\frac{x ^{2} - 1}{x ^{2} - 9}

Factor

x^{2} - 9 : (x + 3) (x - 3)

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

Factor

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

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

\frac{x ^{2} - 1}{x ^{2} - 1}

x - 2 y + a x - 2 a y

4 a - 4 b + a x - b x

3 (a - b)^{2} - 7 (a - b) - 6
