| 1) Solve the following. subtract 9ab + 18bc - 2ac from 19ab - 13bc + 4ca Answer: 10ab Answer: -31bc Answer: 6ca SOLUTION 1 : (19ab - 13bc + 4ca) - (9ab + 18bc - 2ca) = 19ab - 13bc + 4ca - 9ab - 18bc + 2ca = (19ab - 9ab) + (-13bc - 18bc) + (4ca + 2ca) = (19 - 9)ab + (-13 - 18)bc + (4 + 2)ca = 10ab -31bc + 6ca |
| 2) Solve the following. subtract 2ab + 11bc - 16ac from 13ab - 5bc + 16ca Answer: 11ab Answer: -16bc Answer: 32ca SOLUTION 1 : (13ab - 5bc + 16ca) - (2ab + 11bc - 16ca) = 13ab - 5bc + 16ca - 2ab - 11bc + 16ca = (13ab - 2ab) + (-5bc - 11bc) + (16ca + 16ca) = (13 - 2)ab + (-5 - 11)bc + (16 + 16)ca = 11ab -16bc + 32ca |
| 3) Solve the following. subtract 8ab + 9bc - 5ac from 12ab - 16bc + 14ca Answer: 4ab Answer: -25bc Answer: 19ca SOLUTION 1 : (12ab - 16bc + 14ca) - (8ab + 9bc - 5ca) = 12ab - 16bc + 14ca - 8ab - 9bc + 5ca = (12ab - 8ab) + (-16bc - 9bc) + (14ca + 5ca) = (12 - 8)ab + (-16 - 9)bc + (14 + 5)ca = 4ab -25bc + 19ca |
| 4) Solve the following. subtract 4ab + 5bc - 17ac from 14ab - 20bc + 17ca Answer: 10ab Answer: -25bc Answer: 34ca SOLUTION 1 : (14ab - 20bc + 17ca) - (4ab + 5bc - 17ca) = 14ab - 20bc + 17ca - 4ab - 5bc + 17ca = (14ab - 4ab) + (-20bc - 5bc) + (17ca + 17ca) = (14 - 4)ab + (-20 - 5)bc + (17 + 17)ca = 10ab -25bc + 34ca |
| 5) Solve the following. subtract 5ab + 10bc - 9ac from 14ab - 15bc + 16ca Answer: 9ab Answer: -25bc Answer: 25ca SOLUTION 1 : (14ab - 15bc + 16ca) - (5ab + 10bc - 9ca) = 14ab - 15bc + 16ca - 5ab - 10bc + 9ca = (14ab - 5ab) + (-15bc - 10bc) + (16ca + 9ca) = (14 - 5)ab + (-15 - 10)bc + (16 + 9)ca = 9ab -25bc + 25ca |
| 6) Solve the following. subtract 6ab + 19bc - 14ac from 15ab - 16bc + 4ca Answer: 9ab Answer: -35bc Answer: 18ca SOLUTION 1 : (15ab - 16bc + 4ca) - (6ab + 19bc - 14ca) = 15ab - 16bc + 4ca - 6ab - 19bc + 14ca = (15ab - 6ab) + (-16bc - 19bc) + (4ca + 14ca) = (15 - 6)ab + (-16 - 19)bc + (4 + 14)ca = 9ab -35bc + 18ca |
| 7) Solve the following. subtract 3ab + 11bc - 14ac from 14ab - 4bc + 4ca Answer: 11ab Answer: -15bc Answer: 18ca SOLUTION 1 : (14ab - 4bc + 4ca) - (3ab + 11bc - 14ca) = 14ab - 4bc + 4ca - 3ab - 11bc + 14ca = (14ab - 3ab) + (-4bc - 11bc) + (4ca + 14ca) = (14 - 3)ab + (-4 - 11)bc + (4 + 14)ca = 11ab -15bc + 18ca |
| 8) Solve the following. subtract 3ab + 20bc - 17ac from 14ab - 5bc + 8ca Answer: 11ab Answer: -25bc Answer: 25ca SOLUTION 1 : (14ab - 5bc + 8ca) - (3ab + 20bc - 17ca) = 14ab - 5bc + 8ca - 3ab - 20bc + 17ca = (14ab - 3ab) + (-5bc - 20bc) + (8ca + 17ca) = (14 - 3)ab + (-5 - 20)bc + (8 + 17)ca = 11ab -25bc + 25ca |
| 9) Solve the following. subtract 9ab + 4bc - 5ac from 14ab - 4bc + 3ca Answer: 5ab Answer: -8bc Answer: 8ca SOLUTION 1 : (14ab - 4bc + 3ca) - (9ab + 4bc - 5ca) = 14ab - 4bc + 3ca - 9ab - 4bc + 5ca = (14ab - 9ab) + (-4bc - 4bc) + (3ca + 5ca) = (14 - 9)ab + (-4 - 4)bc + (3 + 5)ca = 5ab -8bc + 8ca |
| 10) Solve the following. subtract 4ab + 5bc - 15ac from 19ab - 15bc + 6ca Answer: 15ab Answer: -20bc Answer: 21ca SOLUTION 1 : (19ab - 15bc + 6ca) - (4ab + 5bc - 15ca) = 19ab - 15bc + 6ca - 4ab - 5bc + 15ca = (19ab - 4ab) + (-15bc - 5bc) + (6ca + 15ca) = (19 - 4)ab + (-15 - 5)bc + (6 + 15)ca = 15ab -20bc + 21ca |
