Yeah, it's kind of tricky.
Using 6,1 for factors will make things kind of lop-sided, so I'd go with 2 and 3.
(5x-2)(x+3) = 5x^2 + 13x - 6 Nope
(5x+3)(x-2) = 5x^2 - 7x - 6 Nope
I think we're out of luck. The discriminant is 64+120 = 184, which is not a perfect square, so you can't factor this over the integers.
factorise 5x^2+8x-6
please help... will be much appriciated.
