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:

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this
