solve the quadratic equation by factoring-> x^2+9x-36=0... can someone do this, and give me step by step instructions please!! thax so much!1 xxx
You're trying to put the equation in the form (x-something)*(x-somethingelse)=0 -- does that help?
not really, i havent done this in so long...
Well, if you had to guess at numbers for the two somethings, what would they be? Just take a wild guess at first
What are two numbers that multiply to give 36, but either add or subtract to give 9.
You can check by FOIL'ing it out.
thanks so much!
