12a2/(2ab) = 6a/b
6a2b2c2d2 + 2abcd2 can be factorised to 2abcd2*(3abc + 1)
6(a+b)
-132
It is: 2b squared
-2a^2
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
(a + 2 - b) (a + 2 + b)
4(2a+b) + 2(6a+2b) Working this out it is: 8a + 4b + 12a + 4b = 20a + 8b or 4(5a+2b).
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
(a+b)2
6a square plus b square
