Description: Learn how to apply the distributive property to factor out the greatest common factor from an algebraic expression like 2+4x. Or if you're talking about factored form, you're essentially taking the number and you're breaking it up into the things that when you multiply them together, you get your original number. So if we start with an expression, let's say the expression is two plus four X, can we break this up into the product of two either numbers or two expressions or the product of a number and an expression? Well, one thing that might jump out at you is we can write this as two times one plus two X.*Teacher Advisor is 100% free.
