[<< wikibooks] Basic Algebra/Solving Quadratic Equations/Solving Quadratic Equations by Factoring
== Vocabulary ==


== Lesson ==
The easiest way to solve a quadratic equation is to factor the problem.
Steps: 

Make "Y" a zero.
list all the factors of "a" in y=ax2+bx+c.
List all the factors of "c" in y=ax2+bx+c.
See which factors can be used in such a way that when added or subtracted together they equal "b"


== Example Problems ==
y=x2+2x+1

a=1 1*1=1
c=1 1*1=1
b=2 1+1=20=(x+1)(x+1) or 0=(x+1)2
x=-1
