Answer:
The simplified expression is -2a²b³ + 2a³b - 2ab.
Explanation:
The concept used to simplify the given expression is combining like terms.
By combining the terms with the same variables and exponents, we can simplify the expression.
To simplify the given expression: (-a²b³ + a³b - ab) - (a²b³ - a³b + ab), we can combine like terms:
(-a²b³ + a³b - ab) - (a²b³ - a³b + ab)
= -a²b³ + a³b - ab - a²b³ + a³b - ab
(distributing the negative sign)
= -2a²b³ + 2a³b - 2ab
(combining like terms)
Therefore,
The simplified expression is -2a²b³ + 2a³b - 2ab
