Question 42842
Don't look at it like the answer either has to jump into
your head or it doesn't. Take small steps toward a possible 
solution and test them. If it doesn't work, backtrack and 
try something a little different
{{{2x^2+x-6}}}
Look at the 1st term, {{{2x^2}}}
The simplest factors are 2x and x, since {{{2x*x = 2x^2}}}
So far, you've got
(2x - )(x + ) The signs are opposite, since the 2nd terms
have multiply to equal -6
Try 2*3 for 2nd term factors
{{{(2x - 2)(x + 3) = 2x^2 +4x - 6}}}
That's not it
Try 3*2
{{{(2x - 3)(x + 2) = 2x^2 + x -6}}}
That's it
