Question

Solve. x2 + 6x = 10

-3 ± sqrt 10
-3 ± sqrt 7
-3 ± sqrt 19
-3 ± sqrt 13

Answer 1

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

Answer 2

yes x^2 + 6x = 10

Answer 3

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?

Answer 4

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

Answer 5

hm. I see your problem.

Answer 6

yep.. no idea what to do now

Answer 7

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

Answer 8

you got the answer :)

Answer 9

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

Answer 10

anything even is tricky o_o
