difference of perfect square Differences of perfect squares work because the middle term cancels out x 5 x 5x 2 5x 5x 25 x 2 25 The pattern for squaring something like x 5 2 x 2 10x 25
A difference of square is expressed in the form a 2 b 2 where both the first and last term is perfect squares Factoring the difference of the two squares gives a 2 b 2 a b a b This is true because a b a b a 2 ab ab b 2 a 2 b 2 How to Factor Difference of Squares The following are valid examples of a difference of two squares which can always be factored into a pair of conjugates a b Notice that each term is a perfect square and each starting expression is a mathematical difference 25x 49y factors into 5x 7y 5x 7y z factors into z z 9 p factors into 3

A difference of square is a binomial in which both the terms are perfect squares and they are subtracted a2 b2 if you have a difference of squares expression here is how you would factor it a2 b2 a b a b in this case it is x2 49y2 a x b 7y x2 49y2 x 7y x 7y So we can factor out the greatest common factor first 9 m2 9n6 In the factor m2 9n6 both m2 and 9 n6 are perfect squares and this factor is subtraction It qualifies for use of the difference of squares formula a2 b2 a b a b m2 is the square of m 9 n6 is the square of 3 n3 a m and b 3n3
Factor difference of squares by first factoring out the GCF Factoring a Perfect Square Trinomial A perfect square trinomial is a trinomial that can be written as the square of a binomial Recall that when a binomial is squared the result is the square of the first term added to twice the product of the two terms and the square of the last term Why learn how to factor special cases Some people like to find patterns in the world around them like a game There are some polynomials that when factored follow a specific pattern Perfect square trinomials of the form a2 2ab b2 a 2 2 a b b 2 A difference of squares a2 b2 a 2 b 2
