Question

(x^2- bx- ax + ab)/(x^2+ bx – ax - ab) сократите

Answer 1

$frac{x^{2}-bx-ax+ab}{x^{2}+bx-ax-ab}=frac{x(x-b)-a(x-b)}{x(x+b)-a(x+b)}=frac{(x-b)(x-a)}{(x+b)(x-a)}=frac{x-b}{x+b}$

Answer 2

$frac{x^2-bx-ax+ab}{x^2+bx-ax-ab}=frac{x(x-b)-a(x-b)}{x(x+b)-a(x+b)}=frac{(x-b)(x-a)}{(x+b)(x-a)}=frac{x-b}{x+b}$
