Quadratic Equations

I couldn't find the sets of factors that add up to 13 in this problem. I have to solve this problem by factoring, not anything like the b/2a or anything. Plz help, anything is greatly appreciated!
x^213x+36
Thx for helping ppl!
Emily,
Couldnt it be anything like 2x+15x?
or like
x6.5x+18
You have to find the factors of 1 (coefficient of x^2) and 36 (the constant) that multiply together then add together and make 13. It would work if it were 12 instead, but it's 13. I don't have the answers to this problem, it's off a worksheet so it isn't off of any website. Thx for trying to help me out anyway, Shaydie! U R awesome.

(x  4)*(x9)
Thanks!!!
I got confused while I was figuring out the problem. I wrote it right, but I was trying to figure out what factors of 13 and 36 added up to 13, instead of 1 and 36. I feel so stupid! Anyway, thx for helping, Count Iblis! Happy Valentine's Day
