Answer: x ( y + 1) + y ( y + 3) + 2

Step-by-step explanation:

( x + y + 2) ( y + 1)

x ( y + 1) + y ( y + 1) + 2 ( y + 1)

expanding the bracket

( xy + x) + ( y2 + y) + ( 2y + 2)

removing the bracket

xy + x + y2 +y + 2y + 2

collecting like terms

xy + x + y2 + 3y + 2

given as: x(y + 1) + y ( y + 3) + 2
