Answer 1

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

$( {( \times + 1)}^{2} - (x + 4) {}^{2} + {x}^{2} - 25) = \frac{ {x {}^{2} - 6 x - 40}^{} }{(x - 5)(x + 4)( \times + 1)}$

$\frac{(x - 8)(x + 5)}{(x - 5)(x + 4)(x + 1)}$.

d) (x+1)/(x-5)(x+4) - (x +4 ) / (x-5) + (x+5)/(x+4)(x+1).

((x+1)2 - (x+4)2 +( x2-25))/(x-5)(x+4)(x+1)

(x-8)(x+5) / (x-5)(x+4)(x+1)
