if we are looking to simplify two trinomials, it is easiest to put them on top of each other and subtract.

   7x²  - 2x  + 5                      7x² - 2x + 5
- (3x² + 4x + 10)                  -3x² - 4x - 10

4x² - 6x - 5                   

DessB
-3x^2-4x+14x^-+1-5

this is what I got, hope this helps.
