(6a - 12) - (4a + 4) = ?
Correct answer: D. 2(a-8)
- A. 2(a+2)
- B. 2(a + 4)
- C. 2(a-2)
- D. 2(a-8)
Explanation
To solve this problem, combine like terms, keeping track of the negatives. The expression (6a - 12) - (4a + 4) becomes 6a -12 - 4a - 4, which can be simplified to 2a - 16. The coefficient 2 can be factored out of both terms to get 2(a - 8).
