55/5ab + 4/5ab = 59/5ab
7ab-5ab = 2
gcd of 5ab,28xy
(5ab^2 + 4cd)(5ab^2 4cd) <
(5ab)2 = 25a2b2 (provided a and b are elements of a commutative group).
The GCF of 5ab and 56b squared is b.
6a2 + 5ab - 6b2 = (3a - 2b)(2a + 3b)
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
