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
-2ab
3ab + 3ac + 2b2 + 2bc = 3a(b + c) + 2b(b + c) = (3a + 2b)(b + c)
(a+b)(3b+1)
Provided multiplication is commutative, it is 8ab.
(3b - 1)(a - b)
3a(b+c)+2b(b+c)
It is an algebraic expression because it has no equality sign.
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)
(3a - 2c)(b - d)
6
2a-3ab = -1
