A small square of side q is removed from a large square of side p. Which is the factor form of the remaining area?

Answer and explanation

Correct answer: (p−q)(p+q)

The direct answer is C. The large square has area p² and the removed small square has area q². Thus the remaining area is p² − q². The difference-of-squares identity says p² − q² = (p−q)(p+q), so option C is the required factor form. Option A adds the two square areas instead of subtracting the removed area. Option B is the square of the sum and would represent (p+q)², not the remaining difference. Option C correctly factors the difference into the product of the difference and the sum. Option D, 2pq, is the middle term associated with (p+q)² and is not the leftover area. Memory cue: for U²−V², write (U−V)(U+V).
