Whats a difference of a two square (I just need the definition)

In mathematics, the difference of two squares is a squared (multiplied by itself) number subtracted from another squared number. Every difference of squares may be factored according to the identity

{\displaystyle a^{2}-b^{2}=(a+b)(a-b)}a^2-b^2 = (a+b)(a-b)

but you might wanna put it in your own words
