Consider the expression: (x + 3) • (y + 1) • (x + 2)

Step-by-step explanation:

First we multiply x through (y+1). This equals xy + x.

Second we take 3 through (y+1). This equals 3y+3.

Next we take xy + x through (x+2). This equals 2x squared, y + 2x squared.

Fourth we take 3y+3 through (x+2). This equals 6xy + 6x.
