-5ab + 7ab -9ab + ab -2ab ... Let's simplify that a bit:ab(-5+7-9+1-2) = -8ab
(a - 2b)(2a - b)
The GCF is 4.
55/5ab + 4/5ab = 59/5ab
gcd of 5ab,28xy
35ab squared
7ab-5ab = 2
The GCF of 5ab and 56b squared is b.
35ab
-5ab + 7ab -9ab + ab -2ab ... Let's simplify that a bit:ab(-5+7-9+1-2) = -8ab
(5ab)2 = 25a2b2 (provided a and b are elements of a commutative group).
(2a + b)(a + 3b)
No.
(a - 2b)(2a - b)
The GCF is xy
The GCF is 5.
The GCF is 4x.
