The function \(y=\frac{x^3+8x^2+21x+18}{x+2}\) can be simplified into the function y=Ax^2+Bx+C with a point of discontinuity at x=D. What is the sum of the values of A, B, C, and D?

From the given equation x cannot equal  -2   (that would result in a zero denominator)  so D= -2

 

If yo do the division of this fraction you wind up with   x^2+6x+9       A = 1   B = 6   C = 9    and D = -2

   I think you an take it from here.....cheeky
