FOIL stands for: First Outside Inside Last. These are the terms that must be multiplied when dealing with binomials. If you ignore one of the multiplications, you will lose part of the answer.

x and x^2 are not combinable. If you combine the two then you would have 2x^2 which if factored out is x^2 + x^2 which is not what you started with. So variables with different exponents are not considered "like terms"
'; explain = '#3
The difference of squares creates two center terms that cancel each other out, so there is no center term at all like you normally have.

The Sum of Cubes formula helps to factor cubed terms

The other formula (not sum of cubes) that helps with factoring cubes, is the difference of cubes
