Question

Can someone help me understand sum or difference of two cubes?

Answer 1

Let a and b be two different numbers. For simplicity, let's also assume that they're both integer.

"The cube of a" is expressed as a^3; "the cube of b" is expressed as b^3.

Finding "the difference" is equivalent to subtracting one quantity from another.

So, "the difference of two cubes" could be a^3 - b^3.
