2a + 10 + 5a - 2 = (2a + 5a) + (10 - 2) = 7a + 8
The GCF is a^2.
5a³ - 4ab + 2a³ = (5+2)a³ - 4ab = 7a³ - 4ab.
To simplify the expression (3 - 5(a - 4)), first distribute the (-5) across the terms inside the parentheses: (3 - 5a + 20). Then, combine the constant terms (3 + 20) to get (23 - 5a). Therefore, the simplified expression is (23 - 5a).
It simplifies to 5a+4 !
Add them together: 2a+5a = 7a
2a + 11a - 5a = 8a
2a + 10 + 5a - 2 = (2a + 5a) + (10 - 2) = 7a + 8
5a + 4b - 3a =(5a - 3a) + 4b =2a + 4b =2 (a + 2b)
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)
The GCF is a^2.

5a³ - 4ab + 2a³ = (5+2)a³ - 4ab = 7a³ - 4ab.
To simplify the expression (3 - 5(a - 4)), first distribute the (-5) across the terms inside the parentheses: (3 - 5a + 20). Then, combine the constant terms (3 + 20) to get (23 - 5a). Therefore, the simplified expression is (23 - 5a).
