The special rules
for factoring a perfect square trinomial are a2 + 2ab +
b2 = (a + b)(a + b) and a2 - 2ab + b2
= (a - b)(a - b).
Learn to recognize
perfect square trinomials in more complicated forms. This is an
important skill you will need in later work in this course.
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.
The square root
property states that if x2 = n, then x = √n or x =
-√n. You can use this property to solve some quadratic equations.
