You identify special products by their values if its a perfect square or cubes..

Explanation:

For examples;

Difference of two squares is: x^2 - y^2 = (x + y) (x - y)x2−y2=(x+y)(x−y)

(x + y)^2 = x^2 + y^2 + 2ab(x+y)2=x2+y2+2ab

(x - y)^2 = x^2 + y^2 - 2ab(x−y)2=x2+y2−2ab

Note: (x - y)^2 != x^2 - y^2(x−y)2≠x2−y2
