Complete the square to Solve Quadratic Equation:
Solve the equation. Express the answer in simplest radical form.
x^27x=11
Please Help!!!! Thanks.

x^27x+11=0
you multiply all of it by 1 to change the x into postive.
therefore,
x^2+7x11=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 (:
