    you need to find the derivative of the function use the quotient rule

    the slope will be the derivative and you equate it to -12/25 Then solve for x

    y' = 3(x - 4) - 3x * 1 ------------- (x - 4)^2 = -12 ----- (x - 4)^2

    now this equlas -12/25 so we have -12 -12 ----- = ------ (x - 4)^2 25 Solve this for x.

    as the numerators are both the same we can write (x - 4)^2 = 25

    now its easy once you have found the 2 values of x plug them into the original function to find the y-values of the 2 points.
