# Simplifying a problem.

-This is what I need to simplify.
π((14-2x)/π)2

-This is what I got.
(196+4x)/(π2)

-This is the solution.
(196-56x+4x2)/π

Really unsure of where that -56x is coming from in the solution.

this part
((14-2x)/π)2

(a/b)n=an/bn

so ((14-2x)/π)2 = (14-20)22

The problem is that π((14-2x)/π)2 = n[(14-2x)2/n2] and not n[(142 + (-2x)2)/n2] the way you solved it.

Edit: Got beat to it.
