11-129.

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

How many ones do you need to make a perfect square? How many do you have?

*f*(*x*) = (*x* + 2)^{2} + 2

See part (a).

(*x* + 3)^{2} + (*y* − 4)^{2} = 25

Remember to sketch the equation.
