dybincka [34]
A) this is the simplified form
( {x}^{3}  + 3 {x}^{2}  - 6) + ( {x}^{2} - x + 7) \\  =  {x}^{3}   + 3 {x}^{2}  - 6 +  {x}^{2}  - x + 7 \\  =  {x}^{3}  + 4 {x}^{2}  - x + 1
b)
(5 {x}^{2}  - 4x + 7) - ( {x}^{2}  - 2x - 5) \\  = 5 {x}^{2}  - 4x + 7 -   {x}^{2}  + 2x + 5 \\  = 4 {x}^{2}   - 2x + 12
