7-81.

*y* = 2*x*^{2} − 6*x* + 2 to graphing form and identify the vertex of the parabola. He did the work below and identified the vertex to be (

*y* = 2*x*^{2} − 6*x* + 2

*y* = 2(*x*^{2} − 3*x*) + 2

*y* = 2(*x*^{2} − 3*x *+

*y* = 2(*x* − ^{2} −

Use the Distributive Property to rewrite the third equation. Is it equivalent to the first equation?

It should be.
