expand (x^2+15)/((x-3)(x+3))

expand

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

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

Solution steps

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

Expand

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

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

\frac{( e ^{2 z} )}{( z - 1 ) ^{3}}

(x - 1) \cdot e^{x^{2} - 4}

(5 x^{2} + 2 y) d y

769 (e + 12)

\frac{( 5 x + 3 y ) ( 5 x - 3 y )}{225}
