Quad form-- X= -b +/- square root of B^2- 4(a)(c) over 2(a) a is 1;b is -12; c is 10. Plug in the numbers and solve. I'm not going to be there to take your test for you so you need to know how to do this yourself. If your teacher is worth their salt just knowing the answer will serve no useful purpose. They want you to know HOW you got that answer.

quadratic formula is [-b (+/-) sqrt(b^2-4ac)] / [2a]
you just have to plug the numbers in.
good luck
