Q:
(2x-4)/(x^2-4)+(x-3)/(x^2+5x+6) simplify
Accepted Solution
A:
Answer: 3(x + 1)= ------------------ (x +2)(x + 3)Step-by-step explanation: (2x-4) (x-3)--------------+ ------------------------(x^2-4) (x^2+5x+6) (2x-4) (x-3)= -------------- ----+ ------------------------ (x + 2)(x - 2) (x + 3)(x + 2)GCF = (x +2)(x - 2)(x + 3) (2x - 4)(x + 3) + (x - 3)(x - 2)= ------------------------------------------ (x +2)(x - 2)(x + 3) 2x^2 + 6x - 4x - 12 + x^2 -2x - 3x + 6= ----------------------------------------------------------- (x +2)(x - 2)(x + 3) 3x^2 - 3x -6 = -------------------------- (x +2)(x - 2)(x + 3) 3(x^2 - x - 2)= -------------------------- (x +2)(x - 2)(x + 3) 3(x - 2)(x + 1)= -------------------------- (x +2)(x - 2)(x + 3) 3(x + 1)= ------------------ (x +2)(x + 3)
