ah i don't know how to factor that
What is the common factor?
2 and 4?
ok I will show you one wayS:
(2x )(2x ) first term mult = 4x^2
(2x 1 )(2x 1 ) our last term is +1 it (-1)(-1) or(1) (1)
we know our middle term is 4x=2x+2x we get this by mult outside terms and inside terms so
(2x+1)(2x+1) is our factor
is there any shortcut method
i can't understand that one. how'd u got 2x?
well if you have x^2 you can see it is x times x
4x^2 = 2x
how about the remaining 4x+1 ?
I am using the Foil method in reverse multiply the first outside inside last
so I have to figure out the first terms 2x times 2x is a good bet because it equals 4x^2
