Remove the parentheses from the following expression, and combine like terms: (a + b – c) + 3a – 2c
A. 2a – b + c
B. 4a + b + 3c
C. 4a + b – 3c
D. 2a – b – c
Remove the parentheses from the following expression, and combine like terms: 3(ax + b2 – c) + 2 22
A. –3(ax – b2 + 3c – 6
B. 3ax +3b2 – 3c + 2
C. 3(ax + 3b2 – 3c + 6
D. (ax + b2 – c + 5
To remove the parentheses and combine like terms in the given expression, follow these steps:
1. First, distribute the positive sign outside the parentheses to each term inside:
a + b - c + 3a - 2c
2. Now, combine like terms. Group the "a" terms and the "c" terms together:
(a + 3a) + (b - 2c) - c
3. Simplify the like terms within the grouped expressions:
4a + (b - 2c) - c
4. Finally, combine the remaining like terms:
4a + b - 2c - c
Thus, the equivalent expression with removed parentheses and combined like terms is: 4a + b - 2c - c.
