Which product should tomas choose?
tomas learned that the product of the polynomials (a + b)
(a? - ab + b) was a special pattern that would result in a
sum of cubes, a + b 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
(2x + y)(2x² + 2xy - y)
(2x + y)(4x² + 2xy - y)
(2x + y)(4x2 - 2xy + y)
(2x + y)(2x2 - 2xy + y
