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

simplify

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

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

Solution steps

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

Factor

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

= \frac{( x + 3 ) ( x - 5 )}{x ^{2} - 9}

Factor

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

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

Cancel the common factor:

x + 3

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

(- 5 - 3 i) - (11 - 9 i)

\frac{1600}{8 5}

48 x^{3}

5 0^{3}

(2 x^{2} y^{3})^{3}
