In a square model for \((3x-2y)^2\), two opposite corner rectangles are removed (each corresponds to a product term). What is the combined area of the two removed strips (combined product of the strip parts)?

Answer and explanation

Correct answer: \(-12xy\)

In \((3x-2y)^2=(3x-2y)(3x-2y)\), the two removed corner rectangles each have area \((3x)(-2y)=-6xy\). There are two such opposite rectangles, so combined removed area is \(-6xy+(-6xy)=-12xy\).
