If you mean the negative sign then
2x^2+x-3
If you mean a positive sign and adding
4x^2+3x+5

Simplifying
(3x^2 + 2x + 1) + (x^2 + x + 4)
Reorder the terms:
(1 + 2x + 3x^2) + (x^2 + x + 4)
Remove parenthesis around (1 + 2x + 3x^2)
1 + 2x + 3x^2 + (x^2 + x + 4)
Reorder the terms:
1 + 2x + 3x^2 + (4 + x + x^2)
Remove parenthesis around (4 + x + x^2)
1 + 2x + 3x^2 + 4 + x + x^2
Reorder the terms:
1 + 4 + 2x + x + 3x^2 + x^2
Combine like terms: 1 + 4 = 5
5 + 2x + x + 3x2 + x2
Combine like terms: 2x + x = 3x
5 + 3x + 3x^2 + x^2
Combine like terms: 3x^2 + x^2 = 4x^2
5 + 3x + 4x^2
Final result:
5 + 3x + 4x^2

Subtract from what? Or did you mean to have negative sign between two expressions instead of the positive sign?
