Answer 11

and the third option is to complete the square

\(3x^2+x=6\)

factor out the 3

\(3(x^2+\frac{x}{3})=6\)

we look at the first degree term (\(\frac{x}{3}\)) Divide this term by 2 and then do the following

\(3(x+\frac{1}{3*2})^2=6+3*(\frac{1}{3*2})^2\)

now you can simplify the right hand side, and then divide away the 3 on the left, square root both sides, and solve for x/
