Answer 2

It is option 4.

Explanation:

Key skills needed to solve this problem: Combining like terms and simplifying

1) We have to combine like terms and simplify to the maximum

• We first start with 3xy and - 3xy. These cancel out as they add up to make 0.
• Next. there is y^2 and -y^2. These also cancel out.
• The only 2 terms left are 20 and 10 which add up to make 30.

Therefore, it is option 4.
