...............this problem is wrong. or you typed it wrong. given this it would be 8x = 10. x = 10/8. is it x^2?
anonymous
  • anonymous
yes x^2 + 6x = 10
anonymous
  • anonymous
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?

no... i used the quadratic and i got it to -6 ± sqrt 76 ----------- 2

hm. I see your problem.

  • anonymous
yep.. no idea what to do now
anonymous
  • anonymous
convenient. simplify :). sqrt 76 = 2sqrt(19)

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