Step-by-step explanation:

7) Add to both sides of the equation.

    Add 12y to both sides of the equation.

    Add 18 to both sides of the equation.

    Use the form of to find the values of a, b, and c.

    a = 2, b = 12, c = 18

    Substitute the values of a and b into the formula

    Simplify the bottom.

    d = 3

    Find the value of e using the formula e =

    Raise 12 to the power of 2

    Multiply 4 by 2.

    Divide 144 by 8.

    · 18

    Multiply by 8.

    Subtract 18 from 18.

    e = 0

    Substitute the values of a, d, and e into the vertex form .

    Set x equal to the new right side.

    Use the vertex form, , to determine the values of a h & k.

    a = 2

    h = 0

    k =

    Find the vertex
