simplify (x^2-9)/(x^2+8x+15)

simplify

\frac{x ^{2} - 9}{x ^{2} + 8 x + 15}

\frac{x - 3}{x + 5}

Solution steps

\frac{x ^{2} - 9}{x ^{2} + 8 x + 15}

Factor

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

= \frac{( x + 3 ) ( x - 3 )}{x ^{2} + 8 x + 15}

Factor

x^{2} + 8 x + 15 : (x + 3) (x + 5)

= \frac{( x + 3 ) ( x - 3 )}{( x + 3 ) ( x + 5 )}

Cancel the common factor:

x + 3

= \frac{x - 3}{x + 5}

\frac{( 6 y ^{3} ) ^{4}}{2 y ^{5}}

\frac{3}{5 + 6}

\frac{2}{9} + (- \frac{1}{2})

2 + - 18

(4 m - 5) + (- 6 m - 7 - 2 n)
