1.	x3-19x+30x3x- 40
Answer» (xxx-19x+30)/(xx-3x-40) = (xxx-2xx+2xx-4x-15x+30)/(xx-8x+5x-40) = ((x-2)(x*x+2x-15))/((x-8)(x+5)) = ((x-2)(x+5)(x-3))/((x-8)(x+5)) = ((x-2)(x-3))/(x-8) If you find this answer helpful then like it.

Answer»

(x*x*x-19x+30)/(x*x-3x-40) = (x*x*x-2x*x+2x*x-4x-15x+30)/(x*x-8x+5x-40) = ((x-2)(x*x+2x-15))/((x-8)(x+5)) = ((x-2)(x+5)(x-3))/((x-8)(x+5)) = ((x-2)(x-3))/(x-8)
