Answer 1

29)
a) 
(15X³Y²-10X²Y²):(5X²Y²)=
5X²Y²(3X-2):5X²Y²=3X-2

b)
(12X⁵Y⁴-18X³Y⁵):(6X³Y⁴)=
6X³Y⁴(2X²-3Y):6X³Y⁴=2X²-3Y

c)
(14X⁹Y⁶-21X⁵Y⁸):(-7X⁵Y⁶)=
-7X⁵Y⁶(3Y²-2X⁴):(-7X⁵Y⁶)=3Y²-2X⁴

d)
(25X¹⁰Y⁶-20X⁶Y⁹):(-5X⁶Y⁶)=
-5X⁶Y⁶(4Y³+5X⁴):(-5X⁶Y⁶)=4Y³+5X⁴

e)
(30X¹²Y⁴-24X⁵Y⁹):(-2X⁵Y⁴)=
-2X⁵Y⁴(12Y⁵-15X⁷):(-2X⁵Y⁴)=12Y⁵-15X⁷=3(4Y⁵-5X⁷)

f)
(36X¹¹Y⁵-24X⁷Y⁷):(-4X⁷Y⁵)=
-4X⁷Y⁵(6Y²-9X³):(-4X⁷Y⁵)=6Y²-9X³=3(2Y²-2X³)
