expand (3x)/((x+5)(x+3))

expand

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

\frac{3 x}{x ^{2} + 8 x + 15}

Solution steps

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

Expand

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

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

(2 + i)^{4}

\frac{1}{( 1 + x ) ^{2}}

(x - 2) (x + 2)

(sec (x) + tan (x))^{2}

(x + 2) (x - 2)
