So in this problem, we're being asked to simplify these two expressions that look alike.
00:04
Now, in part a, we're being asked to multiply negative 3 times negative 4a times negative 2.
00:09
So because we're being asked to multiply all three of these terms, we can use the associative property and commuter the property of multiplication to reorder and regroup our terms.
00:19
So when i do that, i'll simply have negative 3 times negative 4 times negative 2, and it'll all get multiplied by a.
00:29
So now i just need to multiply.
00:30
Well, negative 3 times negative 4 is positive 12, and positive 12 times negative 2 is negative 24.
00:37
So i'll just have negative 24a, and that will be the final answer for part a...
