2a + 10 + 5a - 2 = (2a + 5a) + (10 - 2) = 7a + 8
2a-5
5a³ - 4ab + 2a³ = (5+2)a³ - 4ab = 7a³ - 4ab.
(5a+8) - (2a+4) =3a +4 To do this, simply subtract like terms. 5a-2a=3a and 8-4=4
6+7a+6b
2a + 11a - 5a = 8a
Add them together: 2a+5a = 7a
2a + 10 + 5a - 2 = (2a + 5a) + (10 - 2) = 7a + 8
2a² + 6a

2a + 4b
2a + 3a + 4 = 5a + 4
5a + 11
5a³ - 4ab + 2a³ = (5+2)a³ - 4ab = 7a³ - 4ab.
