Not necessarily, but with suitable choice of a, b and y it can be..

6a2 + 5ab - 6b2 = (3a - 2b)(2a + 3b)

3a+5b+7a=

3a + (3b - 2a) + 5b =3a + 3b - 2a + 5b =(3a - 2a) + (3b + 5b) =a + 8b

2a+5b isn't possible the answer is still 2a+5b.

-5ab + 7ab -9ab + ab -2ab ... Let's simplify that a bit:ab(-5+7-9+1-2) = -8ab

7b + 16 = 5b + 247b - 5b = 24 - 162b = 8b = 4

The expression is 5b + 16

No. 2a is one thing, 3b is another. If you add them together, they become 2a + 3b. 5ab indicates that multiplication has taken place. 5 times a times b = 5ab
