expand (4(x+3)(x+1))/((x+5)(x-5))

expand

\frac{4 ( x + 3 ) ( x + 1 )}{( x + 5 ) ( x - 5 )}

\frac{4 x ^{2} + 16 x + 12}{x ^{2} - 25}

Solution steps

\frac{4 ( x + 3 ) ( x + 1 )}{( x + 5 ) ( x - 5 )}

Expand

(x + 5) (x - 5) : x^{2} - 25

= \frac{4 ( x + 3 ) ( x + 1 )}{x ^{2} - 25}

Expand

4 (x + 3) (x + 1) : 4 x^{2} + 16 x + 12

= \frac{4 x ^{2} + 16 x + 12}{x ^{2} - 25}

2 x (x^{3} - 3 x + 7)

(\frac{f}{2} (l - x)) (\frac{w x}{2} (l - x))

3 (6 x + 9 y)^{2} (6 + 9 y^{'} (x))

(3 u^{2}, 3 u^{2}, 2 v) \times (3 v^{2}, - 3 v^{2}, 2 u)

(a^{2} + b^{2} + c^{2} + d^{2})^{2}
