Solving for x in a Simplified Problem: (14-2x)/π = (196+4x)/(π2)

[redbull1990]

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

this part
((14-2x)/π)²

(a/b)ⁿ=aⁿ/bⁿ

so ((14-2x)/π)² = (14-20)²/π²

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.
