| 1) Solve the following. subtract 5ab + 7bc - 19ac from 12ab - 11bc + 5ca Answer: 7ab Answer: -18bc Answer: 24ca SOLUTION 1 : (12ab - 11bc + 5ca) - (5ab + 7bc - 19ca) = 12ab - 11bc + 5ca - 5ab - 7bc + 19ca = (12ab - 5ab) + (-11bc - 7bc) + (5ca + 19ca) = (12 - 5)ab + (-11 - 7)bc + (5 + 19)ca = 7ab -18bc + 24ca |
| 2) Solve the following. subtract 10ab + 4bc - 14ac from 16ab - 17bc + 6ca Answer: 6ab Answer: -21bc Answer: 20ca SOLUTION 1 : (16ab - 17bc + 6ca) - (10ab + 4bc - 14ca) = 16ab - 17bc + 6ca - 10ab - 4bc + 14ca = (16ab - 10ab) + (-17bc - 4bc) + (6ca + 14ca) = (16 - 10)ab + (-17 - 4)bc + (6 + 14)ca = 6ab -21bc + 20ca |
| 3) Solve the following. subtract 7ab + 11bc - 9ac from 16ab - 14bc + 15ca Answer: 9ab Answer: -25bc Answer: 24ca SOLUTION 1 : (16ab - 14bc + 15ca) - (7ab + 11bc - 9ca) = 16ab - 14bc + 15ca - 7ab - 11bc + 9ca = (16ab - 7ab) + (-14bc - 11bc) + (15ca + 9ca) = (16 - 7)ab + (-14 - 11)bc + (15 + 9)ca = 9ab -25bc + 24ca |
| 4) Solve the following. subtract 9ab + 16bc - 2ac from 13ab - 12bc + 17ca Answer: 4ab Answer: -28bc Answer: 19ca SOLUTION 1 : (13ab - 12bc + 17ca) - (9ab + 16bc - 2ca) = 13ab - 12bc + 17ca - 9ab - 16bc + 2ca = (13ab - 9ab) + (-12bc - 16bc) + (17ca + 2ca) = (13 - 9)ab + (-12 - 16)bc + (17 + 2)ca = 4ab -28bc + 19ca |
| 5) Solve the following. subtract 8ab + 19bc - 11ac from 20ab - 11bc + 14ca Answer: 12ab Answer: -30bc Answer: 25ca SOLUTION 1 : (20ab - 11bc + 14ca) - (8ab + 19bc - 11ca) = 20ab - 11bc + 14ca - 8ab - 19bc + 11ca = (20ab - 8ab) + (-11bc - 19bc) + (14ca + 11ca) = (20 - 8)ab + (-11 - 19)bc + (14 + 11)ca = 12ab -30bc + 25ca |
| 6) Solve the following. subtract 6ab + 17bc - 16ac from 22ab - 17bc + 7ca Answer: 16ab Answer: -34bc Answer: 23ca SOLUTION 1 : (22ab - 17bc + 7ca) - (6ab + 17bc - 16ca) = 22ab - 17bc + 7ca - 6ab - 17bc + 16ca = (22ab - 6ab) + (-17bc - 17bc) + (7ca + 16ca) = (22 - 6)ab + (-17 - 17)bc + (7 + 16)ca = 16ab -34bc + 23ca |
| 7) Solve the following. subtract 7ab + 10bc - 11ac from 22ab - 16bc + 10ca Answer: 15ab Answer: -26bc Answer: 21ca SOLUTION 1 : (22ab - 16bc + 10ca) - (7ab + 10bc - 11ca) = 22ab - 16bc + 10ca - 7ab - 10bc + 11ca = (22ab - 7ab) + (-16bc - 10bc) + (10ca + 11ca) = (22 - 7)ab + (-16 - 10)bc + (10 + 11)ca = 15ab -26bc + 21ca |
| 8) Solve the following. subtract 5ab + 14bc - 14ac from 15ab - 5bc + 7ca Answer: 10ab Answer: -19bc Answer: 21ca SOLUTION 1 : (15ab - 5bc + 7ca) - (5ab + 14bc - 14ca) = 15ab - 5bc + 7ca - 5ab - 14bc + 14ca = (15ab - 5ab) + (-5bc - 14bc) + (7ca + 14ca) = (15 - 5)ab + (-5 - 14)bc + (7 + 14)ca = 10ab -19bc + 21ca |
| 9) Solve the following. subtract 3ab + 13bc - 20ac from 18ab - 13bc + 4ca Answer: 15ab Answer: -26bc Answer: 24ca SOLUTION 1 : (18ab - 13bc + 4ca) - (3ab + 13bc - 20ca) = 18ab - 13bc + 4ca - 3ab - 13bc + 20ca = (18ab - 3ab) + (-13bc - 13bc) + (4ca + 20ca) = (18 - 3)ab + (-13 - 13)bc + (4 + 20)ca = 15ab -26bc + 24ca |
| 10) Solve the following. subtract 9ab + 9bc - 11ac from 18ab - 17bc + 20ca Answer: 9ab Answer: -26bc Answer: 31ca SOLUTION 1 : (18ab - 17bc + 20ca) - (9ab + 9bc - 11ca) = 18ab - 17bc + 20ca - 9ab - 9bc + 11ca = (18ab - 9ab) + (-17bc - 9bc) + (20ca + 11ca) = (18 - 9)ab + (-17 - 9)bc + (20 + 11)ca = 9ab -26bc + 31ca |
