So I have 2 questions
1. (-8) x 2/3
2. (-8) x (-2/3)

and  

Step-by-step explanation:

FRACTIONS ARE NOT SCARY.

once you understand this we can dive in and conquer fractions.

we can convert non-fractions into fractions by just slapping a 1 underneath them as a denominator.

and we are looking for (by the way that little star asterisk looking thing * means MULTIPLICATION and is a substitute for "times" like x)

so to multiply fractions lets multiply the numerators -8 and 2. we get -16

now lets also multiply the denominators together and then we get 3

and then our new fraction is

now on to the next question. WAIT! do you have to do this whole process again??? no. they are the same numbers. in this case, both numbers are negative so the result is going to be positive. the answer is

ιт ιѕ (9χ^5+10)(81χ^10-90χ^5+100)
