2ab - 6ac + 3b - 9c = b(2a + 3) - 3c(2a + 3) = (b - 3c)(2a + 3)
(3b + 7x)(3b + 7x) or (3b + 7x)2
(a+b)(3b+1)
6+7a+6b
add like terms: 3a -2a -5b + 6b +3b - 7b = a -3b
2ab - 6ac + 3b - 9c = 2a(b - 3c) + 3(b - 3c) = (2a + 3)(b - 3c).
4a + 3c - 2b - c + a - b = 5a - 3b + 2c
2ab - 6ac + 3b - 9c = b(2a + 3) - 3c(2a + 3) = (b - 3c)(2a + 3)
0.6b + 3c
Gathering like terms together, this is equal to 5a + 3b + 7c.
(2a + 3)(b - 3c)
That's going to depend on the values of 'a', 'b', 'c', and 'f'.
