I have never known how to do these problems and there are plenty on the exam.
A rectangle has an area of (x^3-6x^2+10x-8) square meters and a width of (x-4) meters. What is its length?
How would I set this problem up???
Putting your above values into that question, we get the equation:
What we have now is just a simple polynomial division question.
There are several methods to solve this, I would suggest Synthetic Division, but use whatever method you have been taught.
Hope this helps
