Key Concepts
Property $a^2 b^2 = (a + b)(a b)$. This pattern applies whenever you subtract one perfect square from another. This simple but powerful rule allows you to quickly factor expressions that have only two terms separated by a minus sign, where both terms are perfect squares. It is a fundamental pattern in algebra.
Examples Factor $x^2 81$: $(x + 9)(x 9)$ Factor $16x^2 900$: $(4x + 30)(4x 30)$ Factor $25y^2 4z^2$: $(5y + 2z)(5y 2z)$.
Explanation This is the 'opposites attract' of algebra! When a perfect square is fighting a another perfect square ($a^2 b^2$), they break up into two nearly identical binomials but with opposite signs: $(a+b)$ and $(a b)$. When you multiply them back, the middle terms cancel out perfectly, leaving you right where you started. It's clean and simple!
