2c + 4 - 3c = -9 + c + 5 -c + 4 = c - 4 -2c = -8 2c = 8 c = 4
c + c + 2c + c + c = 6c
6c.
It can be simplified to: 14d+19e

c - 5d = 2 2c + d = 4 Multiply eqn 1 by 2: 2c - 10d = 4 Subtract this from eqn 2: 0c + 11d = 0 which implies that d = 0 Then, by eqn 1, c = 2
4e + 3d + 5e - 5d = 9e - 2d
2c + 4 - 3c = -9 + c + 5 -c + 4 = c - 4 -2c = -8 2c = 8 c = 4
c + c + 2c + c + c = 6c
4ac + 2ad + 2bc +bd = 2a*(2c + d) + b*(2c + d) = (2c + d)*(2a + b)
4c+1-5+2c = 6c-4.
It is: 2c+8
Without any information about a or b or c, all that can be said is: a + b + 2c = a + b + 2c Not particularly illuminating!

24c2 + 96c + 90 = 6*(4c2 + 16c + 15) = 6*(2c + 3)*(2c + 5)
