6a²b - 12ab²
3a + 5b - 6a - 9b = -3a - 4b
12b2 - 8b = 0 4b(3b-2) = 0 4b = 0 and 3b-2 = 0 4b = 0 and 3b = 2 b = 0 and 2/3
It is: 12b2
Well if it is worded right then 4xb-1+(-4)+4b=4b-1-4+4b=4b+4b-1-4=8b-5
1a+3b 2a+4b=3a +7b
3a + 4b - (-6a) - 3b? There is no equivalent because you did not make it an equality. However you could combine the numbers... 3a + 4b +6a -3b = 9a + 1b
Change the order to make it more obvious: 3a - a + 2b + 4b 2a + 6b or 2 (a + 3b).
(5a - 4b) + (2c - 3b - 6c) + a =5a - 4b + 2c - 3b - 6c + a =(5a + a) + (-4b - 3b) + (2c - 6c) =[ 6a - 7b - 4c ].
6b+5a-4b+3a= ? Rearrange it as 5a+3a+6b-4b = 8a+2b
5a + 4b - 3a =(5a - 3a) + 4b =2a + 4b =2 (a + 2b)
9a + 3b - 11a - 4b = -2a -b
1/2
6a²b - 12ab²
-7+3b = 4b-8 3b-4b = -8+7 -b = -1 b = 1
2a + 4b
4b
