(x + 6)(2x - 1)
A quadratic can be factorised if the discriminate (b^2 -4ac) is a perfect square - as it is this case 169 or 13^2

it would be (2x-1)(x+6)
when you multiply it back out you should get:
2x^2+ 12x-x-6...
simplify it:
2x^2+11x-6...and there's your original answer

no.... because the last term is negitive..... the middle terms have to be possitive and negitive...so it has to be (2x-1)(x+6).... leaving a possitive 12 minus one.
