The variables of this equation are your letters: a, b, and c. Variables merely stand in an equation to represent values that we don't know. "Solving" an equation is the process by which we uncover those values.
In this particular case, since there are three variables, we cannot discover their values unless we have two other equivalent equations (a system of equations).
12ab+3ab=15ab
(a+b)(3b+1)
The expression "4a2 3ab" seems to be a combination of terms, but it looks like it may be missing an operator between "4a2" and "3ab." If you meant to add them, it would be written as 4a² + 3ab, which represents a polynomial with two terms. The first term, 4a², has a coefficient of 4 and a degree of 2 in variable 'a', while the second term, 3ab, has a coefficient of 3 and includes both variables 'a' and 'b'. If you meant something else, please clarify!
3a(b+c)+2b(b+c)
It is an algebraic expression because it has no equality sign.
12ab+3ab=15ab
-2ab
(a+b)(3b+1)
(3b - 1)(a - b)
Provided multiplication is commutative, it is 8ab.

Factorizing 3ab + 3ac gives 3a (b + c).Factorizing is to express a number or expression as a product of factors.When factorizing always look for common factors. To factorize (3ab + 3ac) look for the highest factor between the two terms (3a). 3ab + 3ac = 3a (b + c)
