After simplifying (3x^2y+2xy^2-5x^2y+8xy^2), what will be the coefficient of (x^2y)?

Answer and explanation

Correct answer: -2

Only like terms can be added or subtracted. The \(x^2y\) terms are \(3x^2y\) and \(-5x^2y\), so their sum is \((3-5)x^2y=-2x^2y\). Therefore, the coefficient of \(x^2y\) is \(-2\). The terms \(2xy^2\) and \(8xy^2\) are not like terms of \(x^2y\), so they do not affect this coefficient. Exam tip: Before combining terms, check that both the variables and their powers are identical.
