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)
3ab + 3ac + 2b2 + 2bc = 3a(b + c) + 2b(b + c) = (3a + 2b)(b + c)
7ab
(3b - 1)(a - b)
-5ab + 7ab -9ab + ab -2ab ... Let's simplify that a bit:ab(-5+7-9+1-2) = -8ab

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)
12ab+3ab=15ab
That would depend on the plus or minus value of 9ab which has not been given
Two negatives make a positive so your equation simplifies firstly as 4ab + 3ab and finally as 7ab.
(2a + b)(a + 3b)
3ab + 3ac + 2b2 + 2bc = 3a(b + c) + 2b(b + c) = (3a + 2b)(b + c)
(a+b)(3b+1)
7ab
Provided multiplication is commutative, it is 8ab.
