How do we factor m^2+4m+4; the book equation is ax^2+bx+c
I always look at c first. C=4 What are the factors of 4; (2*2) or (4*1).
then there is b= 4, I am looking back at the factors of 4.
This may seem confusing because in this case b=c. We want to know what factors of 4(c) can we add together to get 4(b) which is 2*2 gives us c and 2+2 gives us b.
Then we can start plugging in the numbers we can factor m^2+4m+4 can be factored into (m+2)(m+2) or as Tracey said (m+2)^2.
Then we can take m+2=0, subtract 2 from each side.
m=-2
(m+2)2=0
m=-2
