So I'm doing a question on exponential functions.
And I'm trying to work out x^2-5x-1/9 to put it into two factors. But I don't know which numbers would multiply each other to give -1/9 and leave a difference of -5.

I'm not sure where you're getting the -1/9 from, should be a -6! That'll fix things for you
