Question

how can I divide this http://www.revista.vestibular.uerj.br/lib/spaw2/uploads/images/2011_Discursivo/2011_Disc_Mat_Questao10b.PNG by (x-1)(x+2)

Answer 1

\[\left( x-1 \right)\left( x-2 \right)=x ^{2}-3x+2\]
now you can divide by it.

Answer 2

I did, but I got a wrong answer, it should be x^2-4x+8, but I found 2x^2+6x-2

Answer 3

hi, can you help me?

Answer 4

You must've divided wrong in the first term, since you shouldn't end up with a 2x^2 term. Try it again, and see what you get.
