The equation is .
(subtract 6x from each side)
\(Take out common factor)
\(Apply zero product property: If ab = 0 then a = 0 or b = 0)
\(Add 3 to each side)
\\
The solution set is .
(Apply axis of symmetry formula: )
Substitute values (a = 1, and )
Now we can find y-value, the x-coordinate of the vertex is 3.
\Substitute 3 in the equation of .
Draw a coordinate plane
\Draw the equation .
The vertex is at . Graph the x-intercepts
and the vertex is
,
connecting them with a smooth curve.
The solution set is and graph of the equation is
