Dr. Fraser begins Factoring the Difference of Two Squares by covering what exactly is the difference of two squares before moving into factoring using several techniques which include using the greatest common factor. At the end of the lesson you will be comfortable enough to complete the four video examples.
The special rule
for factoring the difference of two squares is a2 b2
= (a + b)(a b).
rule needs to be applied more than once to completely factor the
require several methods to be factored completely. Always start by
finding the Greatest Common Factor. Then try other methods.
You can solve some
quadratic equations by factoring the trinomial and then using the
zero product property.
