sederhanakan bentuk aljabar berikut -x2 - 2x + 35 / x2 - 25

langkah 1:
-x2-2x+35
-x2-7x+5x+35
(-x2-7x)(5x+35)
x(-x-7)-5(-x-7)
(x-5)(-1)(-x-7)
(x-5)(x+7)
Langkah 2:
x2-25 = (x+5)(x-5)
langkah 3;
-x2-2x+35/x2-25
(x-5)(x+7)/(x+5)(x-5)
(x+7)/(x+5)
----------------

[tex] \frac{ -x^{2} -2x + 35}{ x^{2} -25} [/tex]
[tex] \frac{(-x - 7) (x - 5)}{(x + 5) (x - 5)} [/tex]
[tex] \frac{-x -7}{x + 5} [/tex]
