    x = 7 or x = - 2

    Step-by-step explanation:

    Solve for x over the real numbers:

    x (x - 5) = 14

    Expand out terms of the left hand side:

    x^2 - 5 x = 14

    Add 25/4 to both sides:

    x^2 - 5 x + 25/4 = 81/4

    Write the left hand side as a square:

    (x - 5/2) ^2 = 81/4

    Take the square root of both sides:

    x - 5/2 = 9/2 or x - 5/2 = - 9/2

    Add 5/2 to both sides:

    x = 7 or x - 5/2 = - 9/2

    Add 5/2 to both sides:

    Answer: x = 7 or x = - 2
