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 = y.

step-by-step explanation:

from the given information, we know that the sum of cubes is a^3 + b^3

so if we were to substitute in a and b, the sum of cubes would be:

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.
