# FACTORING A DIFFERENCE OF SQUARES PDF

For, the like terms will cancel. (Lesson ) Symmetrically, the difference of two squares can be factored: x2 − 25 = (x + 5)(x − 5). x2 is the square of x. 25 is the. Intermediate Algebra Skill. Factoring the Difference of Squares. Factor each completely. 1) 9x. 2 − 1. 2) 4n. 2 − 3) 36k. 2 − 1. 4) p. 2 − 5) 2x. 2 − Here are some examples showing the range of expressions that qualify as a difference of squares.

The same applies for the b terms. Let's take a look at a couple more examples. Example 1 Factor the expression x2 - 16 First, let's see if this is, in fact, a difference of factoring a difference of squares problem. There are definitely two terms with a minus sign between them, but is each term a perfect square?

This meets the criteria for the pattern, so we can factor it using the pattern.

Just bring down the 3 in factoring a difference of squares of the parenthesis. We can check this by multiplying everything out. Begin the factoring process by writing two sets of open parentheses: Now find the square root of 4x2, the first term, by finding the square root of 4 and then dividing each exponent by 2.

The square root of 4 is 2. Half of the exponent 2 is 1, thus x2 becomes x1 or x.
