this is not an equation, it probably says to "simplify" it.
how about pretending to see it as :
1(2x²+5x+3)-1(x²+2x+1) , then
Yes it does say simplify it, I'm sorry. I understand how you got that, but what if I had something like this.
You start by ordering the terms. The priority of ordering is
1. name of variable in alphabetical order.
For example, put 2xy before y²
2. power of variable in descending order.
Example: x²y is placed before xy²
3. The constant term will be placed at the end.
After that, you would have collected like terms together. Add/subtract like terms. For example, 2x²y + 4x²y = 6x²y.
3x² + x²y + 4x + 5xy - 2xy + y
Add like terms, if any (5xy-2xy=3xy)
3x² + x²y + 4x + 3xy + y
That is all you can do. You cannot add/subtract unlike terms.
x²y and -2yx² are like terms.
xy and 3x² are unlike terms.
