Question

How do you identify special products when factoring?

Answer 1

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)`

`(x + y)^2 = x^2 + y^2 + 2ab`

`(x - y)^2 = x^2 + y^2 - 2ab`

Note: `(x - y)^2 != x^2 - y^2`
