What is the factored form of 15x plus 32x -28?
15x + 32x - 28 = 47x - 28 = (√47x)2 - (√28)2 = (√47x)2 - (2√7)2 = (√47x - 2√7)(√47x + 2√7)

What is the factorization of the polynomial of x2 - 15x - 56?
This will only give a rational answer when it's +56. Then you're looking for two numbers that add to 15 and multiply to 56. That's 7 and 8. If it's -15x, the answer is (x - 8)(x - 7) If it's +15x, the answer is (x + 8)(x + 7)
