Factoring the expression 3x^2 - 12x

To factor the expression 3x^2 - 12x, we can start by factoring out the greatest common factor, which in this case is 3x. This leaves us with 3x(x - 4). So, the fully factored expression is 3x(x - 4). This process is essential in simplifying expressions and solving equations in algebra.

Remember, factoring is a key skill in algebra and is used in various mathematical concepts. Understanding how to factor expressions will greatly aid in solving more complex algebraic problems.
