As I understood, the problem is:
32x + 9 3 x + 5
——————— – ———— – ———— =
12x2 + x - 6 4x + 3 3x - 2
32x + 9 3 x + 5
———————— – ———— – ———— =
(4x + 3)(3x - 2) 4x + 3 3x - 2
LCD = (4x + 3)(3x - 2)
32x + 9 – 3(3x - 2) – (x + 5)(4x + 3)
———————————————————— =
(4x + 3)(3x - 2)
32x + 9 – 9x + 6 - 4x2 – 23x – 15
————————————————— =
(4x + 3)(3x – 2)
– 4x2 – 4x2
——————––—— or ———————
(4x + 3)(3x - 2) 12x2 + x – 6
