sederhanakan bentuk aljabar berikut! tolong jawab yg no. 2

a. 2p - 6q+2p+9q
= 2p+2p-6q+9q
=4p +3q
b.3ax^-4by^+5ax^+6by^
= 3ax^+5ax^-4by^+ 6by^
= 8ax^ +2by^
c. 8(a^-b^)+5(3a^+4b^)
=8a^ -8b^ +15a^ +20b^
=8a^+15a^-8b+20b^
=23a^ +12b^

2.a.2p-6q+2p+9q=2p+2p-6q+9q=4p+3q
2.b.3ax'-4 by'+5ax'+6by'=3ax'+5ax'-4by'+6by'=8ax'+2by'
2.c.8(a'-b')+5(3a'+4b')=8a'-8b'+15a'+20b'=8a'+15a'-8b'+20b'=23a'+12b'
