It would be much easier to be sure what you mean if you write the equation. You could see this from the faq or at least write 160(1-q/4)(10+q/4). If you type in line, please make sure there are enough parenetheses to be unambiguous. If you mean $160(1-\frac q4)(10+\frac q4)$ it is already factored in one sense. What you probably want is first to multiply it out, giving $160(1-\frac q4)(10+\frac q4)=-10q^2-360q-1600=10(q-4)(q+40)$. To find the factors, you can first factor our the $10$ by inspection, then try factors of 160 to find the roots (see the rational root theorem)
