What is factoring?

What is factoring? Factoring is the process by which one tries to make a mathematical expression look like a multiplication problem by looking for factors.

Both numerical and algebraic expressions can be factored using some specific method(s).

The simplest expressions to factor are of course numerical expressions.

It is not hard to see that 12 = 4 × 3 once you know your multiplication table.

However, factoring a big number like 240 may require a lot more work.

The lesson below about factoring integers will show you how to factor 240 and other big numbers.

Then, you will be ready to factor algebraic expressions such as x2 + 5x + 6 and more complicated expressions using a variety of methods

There are three concepts you will need to understand very well before you attempt to factor an expression
