Two positive intergers have a sum of 17 and a product of 66.What are the intergers?

Answer 1

I'm sure there's a formula for this -- but let's try common sense trial and error.

9 * 8 = 72
7 * 10 = 70
6 * 11 = ?

Answer 2

This is what I have
x=1st interger
17-x= 2nd interger
equation:
x(x-17)=66
x^2-17x-66
then I have to factor it but I don't know the factors that is what I need help with finding that
