    Step-by-step explanation:

    y = 2x^2-5x + 12

    a = 2, b = - 5

    Vertex of X-coordinate = - b/2a

    = - (-5) / 2 (2)

    = 5/4

    Vertex of Y-coordinate = f (5/4)

    = 2 (5/4) ^2 - 5 (5/4) + 12

    = 2 (25/16) - 25/4 + 12

    = 25/8 - 25/4 + 12

    = (25 - 50 + 96) / 8

    = 71/8
