10-158.

Complete the square to change the following equations to graphing form. Then sketch the graph of each equation. Homework Help ✎

*f*(*x*) =*x*^{2}+ 4*x*+ 6*x*^{2}+ 6*x*+*y*^{2}− 8*y*= 0

*f*(*x*) − 2 = *x*^{2} + 4*x* + 6 − 2

Now simplify the right side of the equation and factor.

You will need to complete the square twice, once for *x* and once for *y*.

(*x*^{2} + 6*x* + ?) + (*y*^{2} − 8*y* + ?) = 0 + ? + ?

will allow you to simplify the equation to

(*x* + ?)^{2} + (*y* − ?)^{2} = ?

Don't forget to graph each equation!
