I think the question is asking "what value of y satisfies the equation 15x + 15y = 15x + y ? " If so, the answer is y = 0.
14x2 + 15x + 4 = (7x + 4)(2x +1)
22x
3x2 + 15x + 6 = 3*(x2 + 5x + 2). There are no further rational factors.
(x + 7)(x + 8)
-15x=-5*3x+2 -15x=-15x+2 +15x +15x ----------------- 0=2
The GCF is 15x.

14x2 + 15x + 4 = (7x + 4)(2x +1)
x2+15x+14 = (x+1)(x+14)
-3x + 6 + 15x =11x + 8 ie -3x + 15x - 11x = 8 - 6 ie x = 2
-x - 2 + 15x = 14x - 2
6x - 14 + 15x + 2 =21x - 12or3 (7x - 4)
18x2 + 15x + 2 = (3x + 2)(6x + 1)
2x2 + 15x + 25 = (2x + 5)(x + 5)
15x
