3a + 2b is an expression in algebra. If you make 3a + 2b equal to something then you can find the values of "a" and "b"
Lets say you make 3a + 2b equal to 23
3a + 2b = 23
Now find "a" and "b" to make this equation true...
3(5) + 2(4) = 23
15 + 8 = 23
23 = 23 Correct
So in this case a=5 and b=4
23

8a+2b
It is an expression that can be simplified to: 3a-2b+c
3ab + 3ac + 2b2 + 2bc = 3a(b + c) + 2b(b + c) = (3a + 2b)(b + c)
-2a plus 3b
6b+5a-4b+3a= ? Rearrange it as 5a+3a+6b-4b = 8a+2b
8a+2b
It is an expression that can be simplified to: 3a-2b+c
3ab + 3ac + 2b2 + 2bc = 3a(b + c) + 2b(b + c) = (3a + 2b)(b + c)
It is an algabraic expession without knowing whether or not 2b and 3a are plus or minus
Change the order to make it more obvious: 3a - a + 2b + 4b 2a + 6b or 2 (a + 3b).

7a plus 2b plus 3a plus 5b is equal to 10a plus 7b.
-2a plus 3b
6b+5a-4b+3a= ? Rearrange it as 5a+3a+6b-4b = 8a+2b
3a - 2b
7a-2b
= a + b - 2
