Divide: 9a4b - 15a3b2 + 12a2b3 by - 3a2b - Mathematics

Divide: 9a⁴b - 15a³b² + 12a²b³ by - 3a²b

Sum

9a⁴b - 15a³b² + 12a²b³ by - 3a²b

`= (9"a"^4"b" - 15"a"^3"b"^2 + 12"a"^2"b"^3)/("- 3a"^2"b")`

`= "9a"^4/(- 3"a"^2"b") - (15"a"^3"b"^2)/(- 3"a"^2"b") + (12"a"^2"b"^3)/(- 3"a"^2"b")`

= - 3a² + 5ab - 4b²
