Lorne subtracted 6x3 β 2x + 3 from β3x3 + 5x2 + 4x β 7. Use the drop-down menus to identify the steps Lorne used to find the difference.
1. (β3x3 + 5x2 + 4x β 7) + (β6x3 + 2x β 3)
2. (β3x3) + 5x2 + 4x + (β7) + (β6x3) + 2x + (β3)
3. [(β3x3) + (β6x3)] + [4x + 2x] + [(β7) + (β3)] + [5x2]
4. β9x3 + 6x + (β10) + 5x2
5. β9x3 + 5x2 + 6x β 10
