-2
ok, let's see: (3a-2a) + (2b+5b) +(-c +3c) = a + 7b +2c I think that's right.
3a
3(-2b3pa)
Oh honey, you've got yourself a real math problem there. The equivalent expression for 3a a 4b b is 3a^2 + 4b^2. It's as simple as that, no need to overcomplicate things, darling.
(3+2i)-(3+2i)
1 x1 =1 2x2=4 and it goes on and on bye see you later
a + 7b + 2c
3A + 9B = 3(A + 3B)
Add them together: 3a+4a-a = 6a
a + 3a - 2 + 3a. Add the a + 3a + 3a = 7a. You can't combine the -2 & 7a so the solution is: 7a - 2.
3a+6b are two terms of an expression
2a + 3a + 4 = 5a + 4

ok, let's see: (3a-2a) + (2b+5b) +(-c +3c) = a + 7b +2c I think that's right.
5a + 4b - 3a =(5a - 3a) + 4b =2a + 4b =2 (a + 2b)
