If (x=3) and (y=2), which statement is correct about (x^2y-xy^2) and (xy(x-y))?

Answer and explanation

Correct answer: Both expressions have equal values

Factoring out the common factor \,\(xy\) from \,\(x^2y-xy^2\) gives \,\(xy(x-y)\), which is exactly the second expression. For the given values, the first expression is \,\(3^2\times2-3\times2^2=18-12=6\), while the second is \,\(3\times2\times(3-2)=6\). Hence, both values are equal. The zero option is incorrect because \,\(x-y=1\), not zero. Exam tip: Factor out the common term to compare algebraic expressions quickly.
