expand (x+4)/((x-7)(x+5))

expand

\frac{x + 4}{( x - 7 ) ( x + 5 )}

\frac{x + 4}{x ^{2} - 2 x - 35}

Solution steps

\frac{x + 4}{( x - 7 ) ( x + 5 )}

Expand

(x - 7) (x + 5) : x^{2} - 2 x - 35

= \frac{x + 4}{x ^{2} - 2 x - 35}

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

, (3 x^{2} - 5 x + 1) - (7 x^{2} - 2 x + 4)

\frac{( s + 0.4 )}{s ( s + 0.8 )}

(2 y - 3 x) d x - x d y
