7a^2b+8ab^2 -9a^2b
To simplify the expression 7a^2b + 8ab^2 - 9a^2b, we can combine like terms by adding or subtracting coefficients that have the same base and exponent.
Starting with the coefficients: 7 - 9 = -2
Next, we combine the terms with the same base and exponent:
-2a^2b + 8ab^2
So, the simplified expression is -2a^2b + 8ab^2.
To simplify the expression 7a^2b + 8ab^2 - 9a^2b, we can combine like terms.
The like terms in this expression are the terms that have the same variables raised to the same powers. In this case, we have two terms with the variable "a^2b" and one term with "ab^2".
Combining the terms with "a^2b", we have 7a^2b - 9a^2b, which simplifies to -2a^2b.
So, the simplified expression is -2a^2b + 8ab^2.
