How do I turn this into a quadratic equation such as w^2+5w+6=0? Thanks.

The closest I could get is (x(x+1))/2 - 66=0 or x^2+x1/2 - 66=0

I am not a student in school. I bought an introductory physics book. It requires me to know some algebra. I have an algebra book from a class I took in 2000. I am trying to familiarize myself.

With both of those equations I get stuck solving. What times what equals 0.5 for example? 66 factors 1x66, 2x33, 3x22, 6x11. I can't seem to take this any further.

for example.

0.5x^2 + 0.5x - 66 = 0
(0.5x-2)(0.5x+33)
