What would the product of this equation be?

Question

(x^3 +y^5)(x^3 - y^5)=?

Answer 1

Fred:

As is your previous questions, we know that A²-B²=(A+B)(A-B).  Applying this rule in reverse to the above, we get:  (x³+y⁵)(x³-y⁵) = (x³)²-(y⁵)² = x⁶-y¹⁰

Again, we can obtain the same result by completely multiplying out the two factors.
