    Step-by-step explanation:

    1.) Get the equation in the form y = ax^2 + bx + c.

    2.) Calculate - b / 2a. This is the x-coordinate of the vertex.

    3.) To find the y-coordinate of the vertex, simply plug the value of - b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.

    1.) y = - x^2 - 10x + 24

    2.) - (-10) / 2 (-1) = - 5

    3.) y = - (-5) ^2 - 10 (-5) + 24

    y = - 25 + 50 + 24

    y = 49
