The equation is .

(Take out common factor)

(Apply zero product property: If ab = 0 then a = 0 or b = 0)

(Add 11 to each side)

The solution set is {0, 11}.

(Apply axis of symmetry formula: )

Substitute values (a = 1, and )

Now we can find y-value, the x-coordinate of the vertex is 5.5.

Substitute 5.5 in the equation of .

Draw a coordinate plane

Draw the equation .

The vertex is at . Graph the x-intercepts (0, 0) and (11, 0) and the vertex is , connecting them with a smooth curve.

The solution set is {0, 11} and graph of the equation is
