Divide.

x^2+4x-48/x+8

Here is how I solved this problem:

x(x+4)-48/x+8

(x+4)-48/8

(x+4)-6

x+4-6

x=2

Is this correct?

Thanks.

the correct way ... assuming you meant:

(x^2+4x-48)/(x+8)

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)
