Okay so if

then I can use the quadratic and get

which is or

using that and plugging it back in i get:

so the solution is at (3.193,1.092) correct?

then for the other one,

but which leaves me with an imaginary number. So I'm assuming that it means that just the other one is the solution. Am I right? - Dec 1st 2008, 12:34 PMrunning-gag
