1)
Note that -9 is being multiplied by itself. We simply add the exponents.
(-9)9
2)
I think you meant 15x3 rather than 15x2.
Use long division.
-3x2 + (21/5)x + (47/25)
___________________
(-5x - 3) | 15x3 - 11x2 - 22x - 6
15x3 + 9x2 subtract and bring down the next term
_____________
-21x2 - 22x
-21x2 - (63/5)x subtract and bring down the next term.
_______________
(-47/5)x - 6
(-47/5)x - (47/25)
________________
-103/25
Quotient = -3x2 + (21/5)x + (47/25)
Remainder = -103/25
3) You need to write this question.
