| 1) Solve the following. subtract 6ab + 11bc - 7ac from 15ab - 2bc + 19ca Answer: 9ab Answer: -13bc Answer: 26ca SOLUTION 1 : (15ab - 2bc + 19ca) - (6ab + 11bc - 7ca) = 15ab - 2bc + 19ca - 6ab - 11bc + 7ca = (15ab - 6ab) + (-2bc - 11bc) + (19ca + 7ca) = (15 - 6)ab + (-2 - 11)bc + (19 + 7)ca = 9ab -13bc + 26ca |
| 2) Solve the following. subtract 3ab + 10bc - 15ac from 20ab - 7bc + 2ca Answer: 17ab Answer: -17bc Answer: 17ca SOLUTION 1 : (20ab - 7bc + 2ca) - (3ab + 10bc - 15ca) = 20ab - 7bc + 2ca - 3ab - 10bc + 15ca = (20ab - 3ab) + (-7bc - 10bc) + (2ca + 15ca) = (20 - 3)ab + (-7 - 10)bc + (2 + 15)ca = 17ab -17bc + 17ca |
| 3) Solve the following. subtract 9ab + 9bc - 15ac from 20ab - 2bc + 15ca Answer: 11ab Answer: -11bc Answer: 30ca SOLUTION 1 : (20ab - 2bc + 15ca) - (9ab + 9bc - 15ca) = 20ab - 2bc + 15ca - 9ab - 9bc + 15ca = (20ab - 9ab) + (-2bc - 9bc) + (15ca + 15ca) = (20 - 9)ab + (-2 - 9)bc + (15 + 15)ca = 11ab -11bc + 30ca |
| 4) Solve the following. subtract 10ab + 16bc - 11ac from 22ab - 5bc + 10ca Answer: 12ab Answer: -21bc Answer: 21ca SOLUTION 1 : (22ab - 5bc + 10ca) - (10ab + 16bc - 11ca) = 22ab - 5bc + 10ca - 10ab - 16bc + 11ca = (22ab - 10ab) + (-5bc - 16bc) + (10ca + 11ca) = (22 - 10)ab + (-5 - 16)bc + (10 + 11)ca = 12ab -21bc + 21ca |
| 5) Solve the following. subtract 10ab + 9bc - 4ac from 19ab - 2bc + 15ca Answer: 9ab Answer: -11bc Answer: 19ca SOLUTION 1 : (19ab - 2bc + 15ca) - (10ab + 9bc - 4ca) = 19ab - 2bc + 15ca - 10ab - 9bc + 4ca = (19ab - 10ab) + (-2bc - 9bc) + (15ca + 4ca) = (19 - 10)ab + (-2 - 9)bc + (15 + 4)ca = 9ab -11bc + 19ca |
| 6) Solve the following. subtract 8ab + 20bc - 13ac from 17ab - 20bc + 4ca Answer: 9ab Answer: -40bc Answer: 17ca SOLUTION 1 : (17ab - 20bc + 4ca) - (8ab + 20bc - 13ca) = 17ab - 20bc + 4ca - 8ab - 20bc + 13ca = (17ab - 8ab) + (-20bc - 20bc) + (4ca + 13ca) = (17 - 8)ab + (-20 - 20)bc + (4 + 13)ca = 9ab -40bc + 17ca |
| 7) Solve the following. subtract 3ab + 3bc - 7ac from 22ab - 18bc + 14ca Answer: 19ab Answer: -21bc Answer: 21ca SOLUTION 1 : (22ab - 18bc + 14ca) - (3ab + 3bc - 7ca) = 22ab - 18bc + 14ca - 3ab - 3bc + 7ca = (22ab - 3ab) + (-18bc - 3bc) + (14ca + 7ca) = (22 - 3)ab + (-18 - 3)bc + (14 + 7)ca = 19ab -21bc + 21ca |
| 8) Solve the following. subtract 3ab + 4bc - 2ac from 15ab - 14bc + 3ca Answer: 12ab Answer: -18bc Answer: 5ca SOLUTION 1 : (15ab - 14bc + 3ca) - (3ab + 4bc - 2ca) = 15ab - 14bc + 3ca - 3ab - 4bc + 2ca = (15ab - 3ab) + (-14bc - 4bc) + (3ca + 2ca) = (15 - 3)ab + (-14 - 4)bc + (3 + 2)ca = 12ab -18bc + 5ca |
| 9) Solve the following. subtract 7ab + 3bc - 13ac from 21ab - 19bc + 10ca Answer: 14ab Answer: -22bc Answer: 23ca SOLUTION 1 : (21ab - 19bc + 10ca) - (7ab + 3bc - 13ca) = 21ab - 19bc + 10ca - 7ab - 3bc + 13ca = (21ab - 7ab) + (-19bc - 3bc) + (10ca + 13ca) = (21 - 7)ab + (-19 - 3)bc + (10 + 13)ca = 14ab -22bc + 23ca |
| 10) Solve the following. subtract 2ab + 14bc - 2ac from 13ab - 11bc + 17ca Answer: 11ab Answer: -25bc Answer: 19ca SOLUTION 1 : (13ab - 11bc + 17ca) - (2ab + 14bc - 2ca) = 13ab - 11bc + 17ca - 2ab - 14bc + 2ca = (13ab - 2ab) + (-11bc - 14bc) + (17ca + 2ca) = (13 - 2)ab + (-11 - 14)bc + (17 + 2)ca = 11ab -25bc + 19ca |
