6a²b - 12ab²
It is: 12b2
12b2 - 8b = 0 4b(3b-2) = 0 4b = 0 and 3b-2 = 0 4b = 0 and 3b = 2 b = 0 and 2/3
8b - 4b = 4b
Well if it is worded right then 4xb-1+(-4)+4b=4b-1-4+4b=4b+4b-1-4=8b-5
2a + 4b
2a-3+4b-2a-b-2a-b-3+5 Can be simplified to: 3b-1
5a + 4b - 3a =(5a - 3a) + 4b =2a + 4b =2 (a + 2b)
3b -1
2a-4b = -2
2a + 4b - 52a + 4b - 52a + 4b - 52a + 4b - 5
Change the order to make it more obvious: 3a - a + 2b + 4b 2a + 6b or 2 (a + 3b).
12bc - 4bd - 15xc + 5xd = 4b(3c - d) - 5x(3c - d) = (3c - d)(4b - 5x)
The like terms are sums of b terms and c terms separately 5c+2c+3c+4b 5c +2c + 4b + 3c => 10c + 4b
a=2b 4b=6c becomes 2b=3c a=3c
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
2a-3+4b-2a-b-3+5=3b-1
