Please Help!!!! Thanks.

**Me (:**, Wednesday, November 18, 2009 at 9:55pm-x^2-7x+11=0

you multiply all of it by -1 to change the x into postive.

therefore,

x^2+7x-11=0

then apply this to the fo9rmula

-b+- the sqaure root of (b^2 - 4*a*c)/2a

where a = 1

b=7

c=-11

work out the answer, its very easy (:
