Answer:
y²+xy+x+3y+2.
Step-by-step explanation:
Given that,
(x + y + 2)(y + 1)
We will multiply the first bracket variable with the second bracket variable.
i.e, the x with y+1, and the y with y+1, and 2 with y+1.
Therefore,
x(y+1)+y(y+1)+2(y+1)
xy+x+y²+y+2y+2
Collecting like terms and rearranging
y²+xy+x+y+2y+2
y²+xy+x+3y+2 Answer
