This expression matches the identity template a square – 2ab + b square. The middle variable terms cancel out completely when multiplying p/4 and 4/p, leaving only the constant integer minus 2.
We factor this variable fraction expression by recognizing the underlying square identity. The first term is the square of p/4, and the final term 16/p square is the square of 4/p. The middle term is negative, and when we calculate two times p/4 times 4/p, the variables cancel out perfectly to leave just the number two. This gives us the final factored expression (p/4 – 4/p) square.
