In algebra class, factoring the difference between two squares is bound to come up sooner or late.

The difference of two squares always has two squared terms, like a^2 – 16 or x^2 – 9. Some people call it a square minus a square.

Whenever you have this pattern, you can easily factor the problem.

Factoring the difference of two squares is a useful skill to learn in your algebraic education. Having this skill is useful when solving quadratic equations and then finding where parabolas cross the x axis. So be on the lookout for them!
