simplify (x^2-9x-22)/(x^2-121)

simplify

\frac{x ^{2} - 9 x - 22}{x ^{2} - 121}

\frac{x + 2}{x + 11}

Solution steps

\frac{x ^{2} - 9 x - 22}{x ^{2} - 121}

Factor

x^{2} - 9 x - 22 : (x + 2) (x - 11)

= \frac{( x + 2 ) ( x - 11 )}{x ^{2} - 121}

Factor

x^{2} - 121 : (x + 11) (x - 11)

= \frac{( x + 2 ) ( x - 11 )}{( x + 11 ) ( x - 11 )}

Cancel the common factor:

x - 11

= \frac{x + 2}{x + 11}
