Simplify the expression by combining like terms
10ab+2ab2-9ab
3ab+2ab^2
To simplify the expression by combining like terms, add together the coefficients of the terms that have the same variables.
The terms in the expression are:
10ab, 2ab^2, and -9ab.
The coefficients of the terms with "ab" are:
10, 2, and -9.
Add the coefficients together:
10 + 2 - 9 = 3.
So, the simplified expression is:
3ab^2.
