2a + 10 + 5a - 2 = (2a + 5a) + (10 - 2) = 7a + 8
The GCF is a^2.
5a³ - 4ab + 2a³ = (5+2)a³ - 4ab = 7a³ - 4ab.
2a+5
It simplifies to 5a+4 !
Add them together: 2a+5a = 7a
2a + 11a - 5a = 8a
5a + 4b - 3a =(5a - 3a) + 4b =2a + 4b =2 (a + 2b)
2a + 10 + 5a - 2 = (2a + 5a) + (10 - 2) = 7a + 8
21a - 6a
2a² + 6a
2a + 4b
(6a3 - 19a2 + 15a)/(2a - 3) = a(6a2 - 19a + 15)/(2a - 3) = a(2a - 3)(3a -5)/(2a -3) = a(3a - 5)
-6(a-3b-9c)
The GCF is a^2.
5a³ - 4ab + 2a³ = (5+2)a³ - 4ab = 7a³ - 4ab.
5a^(3) if the x means multiplication. 5a^(3)x^(3) if the x is a variable.
