• 

what is factoring

• is a technique that consists of factoring an algebraic expression (which can be a number, an addition or a subtraction)
• 

identify a perfect square difference

• The first thing we have to do is see that it is a difference of squares then that there is a subtraction and that there are two terms and that the two terms can be squared, this is done mentally by taking the square root of the two terms
• 

How do I factor?

• in this case I am going to factor with the example of m2 - 1
• then the square root of m2 is m let's remember that when it is a letter with an exponent the square root is simply dividing the exponent by 2 then 2 divided into 2 by 1 and the square root of 1 is 1 because because one by one this is what we are going to place in the two parentheses then we open two parentheses we place the m and the 1 in the two parentheses and in one parenthesis we have to place the negative sign and in the other the positive one, the order does not matter
