Bantu y jgn lupa pke carany mkshh....

d.15d+3e-3d
=12d+3e

e.8mn+3m-mn
=7mn+3m

f.8pq-p-2q-pq
=6pq-p-pq

d.6a^3+a-a^3+4a
=5a^3+5a

e.k^2-9k^3+7k^2-k^3
=8k^2-10k^3

f.m^2-3m-2m^3-3m^2
=-2m^2-2m^3-3m

1. 15d+3e-3d= 12d+3e
2. 8mn+3m-mn= 7mn+3m
3. 8pq- p- 2q- pq= 7pq -p- 2q
4.6a³ +a - a³+4a = 5a³+5a
5. k²- 9k³ +7k² - k³= -10k³+8k²
6. m²-3m - 2m³-3m² = -2m³-2m²-3m

maaf kalo salah
