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

expand

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

\frac{x ^{2} + 15}{x ^{3} + 3 x + 3 x ^{2} + 9}

Solution steps

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

Expand

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

= \frac{x ^{2} + 15}{x ^{3} + 3 x + 3 x ^{2} + 9}

π (- 4 cos (x) + 4)

(3 e^{t} cos (t) - 3 e^{t} sin (t))^{2}

\frac{( s + 13 )}{s ^{2} ( s ^{2} + 6 s + 10 )}

d x (x + 1) (x - 1) (x - 2)
