200x^2 - 50 -->factor out 50
50(4x^2 - 1) -->difference of perfect squares
50(2x + 1) (2x - 1) --> your factored binomial
difference of perfect squares if you have a^2-b^2 then you factor it as such: (a - b) (a + b)
in this case 4x^2 would be a^2, so 2x would be a and 1 is b^2 and so 1 is b.

200x^2 - 50?
= oh I don't know, I'm trying and I keep on getting the wrong answer.
(x + ) (x - )......
Hmm, this can't be a difference of squares can it? I mean
√50 = is not even
sorry, I feel dumb. =\
Oh wait I think I got it....
(2x - 1) (100x + 50)
check= 200x^2 + 100x -100x − 50.
both 100x's cancel out leaving us with...
200x(squared) − 50.

you would do (200x) x (200x) (-50) so that would be
-200,000x to the second power
