I do not know how to do this problem. Don't know where to start. [(5)/(2x-8)]+[(3x^2+15)/(x^3-4x^2+5x-20)] |
Hi Pricilla.
Factor the denominators of the two terms, then you can simplify, create a common denominator and add the numerators.
Hint: the fraction with the cubic can be simplified to just linear terms top and bottom, so don't look for anything hard. If you guess, you'll probably find that you are right.
