Question

Simplifica fractia F(x)=x^{2} -5x+6asupra lui x la a 2 -4

va rog !!!urgent!!

Answer 1

F(x)=$\frac{x^2-2x-3x+2ori3}{(x-2)(x+2)}$
       =$\frac{x(x-2)-3(x-2)}{(x-2)(x+2)}$
       =$\frac{(x-2)(x-3)}{(x-2)(x+2)}$
       =$\frac{x-3}{x+2}$

Sper ca te-am ajutat! ^..^

Answer 2

(x² - 5x + 6 ) / (x² - 4) =
(x² - 3x - 2x +6) / [(x-2)(x+2)]  = 
[x(x - 3) - 2(x - 3)] / [(x+2)(x-2)]
[(x-3)(x-2)] / [(x+2)(x-2)] = 
(x - 3) / (x +2)
