Tomas learned that the product of the polynomials (a + b)(a2 – ab + b2) was a special pattern that would result in a sum of cubes, a3 + b3. His teacher put four products on the board and asked the class to identify which product would result in a sum of cubes if a = 2x and b = 1. Which product should Tomas choose?

if a = 2x and b = 1 (2x)³+1³ = (2x+1)(4x²-2x+1) I hope this helps
