-----------------------------------
9xkuadrat - 25

Corneliusfranc -6x^2 + 22x - 20 =
(-6x+10)(x-2)/9x^2-25 =
= 2(-3x+5)(x-2)/(-3x+5)(-3x-5)
= 2(x-2)/(-3x-5)
= 2x-4/-3x-5

kevinliyansah $\frac{-6x^2 + 22x - 20}{9x^2 - 25} = \frac{6x^2 - 22x + 20}{(3x-5)(3x+5)} = \frac{(3x-5)(2x-4)}{(3x-5)(3x+5)} = \frac{2x-4}{3x+5}$
