2a + 10 + 5a - 2 = (2a + 5a) + (10 - 2) = 7a + 8
Whan a = 2 and b = 6, 5a + 2b = 5*2 + 2*6 = 10 + 12 = 22
5a plus 2b
6+7a+6b
5a³ - 4ab + 2a³ = (5+2)a³ - 4ab = 7a³ - 4ab.
5a + 4b - 3a =(5a - 3a) + 4b =2a + 4b =2 (a + 2b)
8a+2b
Well if you are adding you would have 8a+2b subtract you would have -2a+2b
no
-2a plus 3b
6b+5a-4b+3a= ? Rearrange it as 5a+3a+6b-4b = 8a+2b
5a(a+2b+b²)
Add them together: 2a+5a = 7a
4a + 3c - 2b - c + a - b = 5a - 3b + 2c
2a² + 6a
2a + 10 + 5a - 2 = (2a + 5a) + (10 - 2) = 7a + 8
It is an algabraic expession without knowing whether or not 2b and 3a are plus or minus
