Thread: ok, how do you know when to group these?

ok thanks to mr fantastic i know pretty much how to work these problems but there is still one small area im being confused with however

for example, if the problem was like this

3q^2 + 14q + 11

i'd then need a set of integers that's sum is 14 and product is 33

the answer to that is 3 and 11.

which one comes first though when you bring the problem down? How do you know which one comes first? for example would you group 11 or 3 with 3q^2?

thanks

hmm guess it doesn't. the 2nd formula i had wrong where you put q as the divisor i couldnt find anything to go as the divisor but i get it now
