1. 4 a 2 b + 5 − 6 a 3 b − 3 a 2 b + 2 a 3 b = = − 6 a 3 b + 2 a 3 b + 4 a 2 b − 3 a 2 b + 5 = = − 4 a 3 b + a 2 b + 5
4a²b + 5 - 6a³b - 3a²b + 2a³b
We first simplify similar expressions,
4a²b - 3a²b + 5 -6a³b + 2a³b
= a²b + 5 - 4a³b
To simplify the polynomial 4 a 2 b + 5 − 6 a 3 b − 3 a 2 b + 2 a 3 b , we combine like terms to get − 4 a 3 b + a 2 b + 5 . This involves adding and subtracting the coefficients of terms that share the same variables. The final simplified expression is − 4 a 3 b + a 2 b + 5 .
