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
