...............this problem is wrong.
or you typed it wrong.
given this it would be 8x = 10.
x = 10/8. is it x^2?

anonymous · Answer

yes x^2 + 6x = 10

anonymous · Answer

OK, so, we're solving for x, right? So you start by subtracting 10 from both sides getting you 

x^2 + 6x - 10 = 0. 

Are there any factors of 10 and 1 that can get you 6?

anonymous · Answer

no... i used the quadratic and i got it to 
-6 ± sqrt 76

         2

anonymous · Answer

hm. I see your problem.

anonymous · Answer

yep.. no idea what to do now

anonymous · Answer

convenient. simplify :). sqrt 76 = 2sqrt(19)

anonymous · Answer

you got the answer :)

anonymous · Answer

OK. Well, what about pulling out 4 (well, 2), and getting rid of it...or Ronncc did it...that was fast...

anonymous · Answer

anything even is tricky o_o
