Question

Find the answer to
(x + y + 2)( y + 1)

Answer 1

I assume the question asks to expand the expression to individual terms.
There are different ways to approach this, all based on FOIL or similar methods.
I prefer to split it into two parts, as follows:
(x+y+2)(y+1)
=x(y+1)+(y+2)(y+1)
=xy+x+y^2+3y+2

Answer 2

Answer:
`(x + y + 2)( y + 1)=xy+y^2+3y+x+2`

Explanation:

The given expression:
`(x + y + 2)( y + 1)`

Using left distributive property:

`a(b+c)=ab+ac`, where a, b, c are any arbitrary expressions.

`\Rightarrow (x + y + 2)( y + 1)=(x+y+2)y+(x+y+2)(1)\\\\=`

Using right distributive property:

`(b+c)a=ba+ca`, where a, b, c are any arbitrary expressions.

`\Rightarrow(x+y+2)y+(x+y+2)(1)=xy+y^2+2y+x+y+2=xy+y^2+3y+x+2`

Hence,
`(x + y + 2)( y + 1)=xy+y^2+3y+x+2`
