Answer 1

they are all right :D

Answer 2

Thanks! :) Can you help me with the last one?

Answer 3

for the last part I suppose you could say that
one way is take the exponent of the denominator (which is 1) and subtract it from the exponent of all other like terms (i.e. all the x's)
another is to factor out the GFC of the numerator (which is x) and divide that by the denominator
you could check your answer by seeing if plugging in x=1 (or any x besides 0) before and after simplifying gives the same result

Answer 4

Thanks so much!! :)

Answer 5

two ways to simplify: (1) factor out a common term (2) use polynomial division to divide the denominator into the numerator.

To check the result, you could multiply the simplified polynomial by the factor and see if you get the original polynomial.

Answer 6

Thank you :)

Answer 7

I really appreciate it! :)
