Question

E(x)= (x/ x-5   -   2/x+5    + x-6/ x² - 25) : x ² - x - 2 / x ² -6x - 5

Answer 1

[ x(x+5)/ (x+5)(x-5) - 2(x-5)/x+5 + x-6/  (x+5)(x-5) ] : (x-2) (x+1)/(x-5)(x-1)
[(x²+5x-2x+10+x-6)/ (x+5)(x-5)] : (x-2) (x+1)/(x-5)(x-1)
[(x²+4x+4)/ (x-5)(x+5)] : (x-2) (x+1)/(x-5)(x-1)
(x+2)²/  (x-5)(x+5) * (x-5)(x-1)/(x-2) (x+1)
(x+2)²/  (x+5) * (x-1)/(x-2) (x+1)
te rog sa verifici daca ai transcris corect , pentru ca nu prea se simplifica expresia asta
