(-a-6b +4)3ab
The answer I got was 3(-a-6b+4)ab
( - a - 6 b + 4 ) 3 a b =
( - a ) * 3 a b - 6 b * 3 a b + 4 * 3 a b =
- 3 a ^ 2 * b - 18 a * b ^ 2 + 12 ab
To simplify the expression (-a-6b + 4)3ab, you need to distribute the 3ab to each term inside the parentheses.
Let's break it down step by step:
1. Distribute the 3ab to -a:
(3ab) * (-a) = -3a^2b
2. Distribute the 3ab to -6b:
(3ab) * (-6b) = -18ab^2
3. Distribute the 3ab to 4:
(3ab) * 4 = 12ab
Putting it all together, the simplified expression is:
-3a^2b - 18ab^2 + 12ab
So, the answer you got, 3(-a-6b+4)ab, is incorrect. The correct simplified expression is -3a^2b - 18ab^2 + 12ab.
