i still don't get how do you divide
(3q cubed +q+6)/(q2)
help!=]
i also need help in...
the volume of a rectangular prism is
2x cubed + x 2. the height of the prism is 2x1, and the length of the prism is x+2. find the width of the prism.
im confused

drwls,
To answer your first question, you need to review polynomial long division. You will be left with a remainder.
I got the answer to be
3q^2 +6q +12 + [30/(q2)]
The term in brackets is the remainder
For your second question, the answer will be the volume divided by the area of the side that you know, or
(2x^3 +x 2)/(2x^2 +3x 3)
This also results in a remainder term. The denominator is not a monomial factor of the numerator.
The assigned you a pair of rather messy problems.
