I am asked to factor 2x^2+13x-24

I multipled -24 and 2 and came to -48 and found that 16 and -3 were the solutions because they equal the X coifficient when added.

My question is this - When I rewrite the equation where do I stick the 16 and the -3

should it be 2x^2+16x-3x-24

or

should it be 2x^2-3x+16x-24

Is this a contstant? Does the largest/smallet number always get plugged in first?

Thanks!!!!!
