    To find the vertex, use the vertex formula: x=-b/2a

    a=1, b=-2, c=3

    x = - (-2) / 2 (1)

    x=1

    The x-coordinate of the vertex is 1.

    To find the y-coordinate, plug in 1 for every x in the equation:

    y = (1) ^2-2 (1) + 3

    y=1-2+3

    y=2

    The y-coordinate is 2.

    The vertex is (1,2)
