1)
3a+4b-15c ; 12b-7c-6a
=
3a + 4b - 15c + 12b - 7c - 6a
=
-3a + 16b - 22c
(2)
3y²-2y²-7y+5 ; 6-4y+y³-5y²
=
3y² - 2y² - 7y + 5 + 6 - 4y + y³ - 5y²
=
y³ - 4y² - 11y + 11
3a+4b-15c ; 12b-7c-6a
=
3a + 4b - 15c + 12b - 7c - 6a
=
-3a + 16b - 22c
(2)
3y²-2y²-7y+5 ; 6-4y+y³-5y²
=
3y² - 2y² - 7y + 5 + 6 - 4y + y³ - 5y²
=
y³ - 4y² - 11y + 11
