What is obtained after simplifying (9u^2v-5uv+3u^2v+8uv-10)?

Answer and explanation

Correct answer: \(12u^2v+3uv-10\)

Only like terms can be combined. The terms \(9u^2v\) and \(3u^2v\) are like terms, so their sum is \(12u^2v\). Similarly, \(-5uv+8uv=3uv\), while the constant term \(-10\) remains unchanged. Therefore, the simplified expression is \(12u^2v+3uv-10\). In option A, the coefficients of the \(uv\) terms have been combined incorrectly. Exam tip: before combining terms, check that both the variables and their powers are exactly the same.
