The LCM is 280a4b2.
7ab
6a2 + 5ab - 6b2 = (3a - 2b)(2a + 3b)
x^3 - 121x
Assuming that non-leading numbers are exponents, the expression becomes12a^2b + 8a - 5a^2b + 2ab - 4ab^2 + 6ab - 2a - 3ab= 7a^2b + 6a + 5ab - 4ab^2= a*(7ab + 6 + 5b - 4b^2)
35ab
35ab squared
7ab-5ab = 2
-5ab + 7ab -9ab + ab -2ab ... Let's simplify that a bit:ab(-5+7-9+1-2) = -8ab
The LCM is 280a4b2.
The GCF of 5ab and 56b squared is b.
(5ab)2 = 25a2b2 (provided a and b are elements of a commutative group).
(2a + b)(a + 3b)
No.
(a - 2b)(2a - b)
LCM(7ab, 8a3b2, 10a4) = 280a4b2
