difference of a and b means a-b
difference of two cubes means a^3 - b^3
That would be 64-y^3 or y^3-27
difference means a-b
cube of difference is (a-b)^3
that would be (y^2-9)^3 or (y-1)^3
(a) Which of the following are examples of the expression "difference of two cubes"? (Select all that apply.)
(y2 - 9)3
3 - 4y
64 - y3
(y - 1)3
y3 - 27
27 - 3y
y3
(b) Which of the following are examples of the expression "cube of a difference"? (Select all that apply.)
27 - 3y
(y - 1)3
(y2 - 9)3
y3
y3 - 27
64 - y3
3 - 4y
