Question 288435
So why do you think 4x+6 +29/(x-4) is wrong, if you got it twice?

It is obviously wrong since there is no x^2 term. The remainder is over (x-4) but you were dividing by (x-2)
and (x-4) into 3x^3 will obviously start out 3x^2
I suspect that you are scamming us. That you didn't even try.
