**Reiny**, Monday, September 28, 2009 at 1:09pmno, you are doing some very "creative" math there

let's multiply each term by x+4, that will cancel out the x+4 in the first two terms

x + 4 + 2(x+4) = 0

3x = -12

x = -4

BUT, when we test this answer, we would be dividing by zero, which of course if a big NO-NO

So the answer we got, does not work, so there is no solution.

Your book is right.
