Can someone check my algebra answers and help me with the problems I don't understand?
1. n^2-n-20/2n^2 times n^2+5n/n^2-25
3. 5x-3/6 - x+3/6
4. 5x/26 - 2x/13
answer: I'm not to sure but i think its x-3/2x^2
8. What values for x must be excluded in the following fraction?
9. x-13/x^2-x-12 + 3x-3/x^2-x-12
Sometimes it helps to use parentheses when typing these kinds of problems online. From what I can determine, these answers look correct, except for #3. (For #4, you can just state the answer as x/26.)
Here's #3 worked out:
(5x-3)/6 - (x+3)/6 =
I hope this will help.
