I'm assuming that's +60. If that's true, the answer is (2x - 10)(2x - 6)

Factor out the GCF, which is 2. That leaves x2 + x - 30. Then you're looking for factors of thirty that differ by one. That would be 5 and 6.
2(x - 5)(x + 6)
The factorisation is as follows: 2x2 + 7x - 9 = (x - 1)(2x + 9).
If that's +28, the answer is (x - 4)
2(x - 6)(x + 6)
If you mean: 2x2+7x+5 then it is (2x+5)(x+1) when factored
6ab(2x2+x-5)
