Did I do this problem right?
Here is how I solved this problem:
Is this correct?
Sorry to say this, but looking at that "solution" made me shudder.
the correct way ... assuming you meant:
Using long algebraic division, one gets
x - 4 with a remainder of -16
or you can use synthetic division to arrive at the same answer.
(x^2+4x-48)/(x+8) = (x-4) - 16/(x+8)
study this example
