Solve for v in v^2 - (v/4)^2 = 196

Homework Statement

I'm solving for v in:

v^2 − (v/4)^2 = 196

→v^2(1-(1/4))=196

→v^2(.75)=196 → √(196/.75)≈16.17

What did I do wrong?
I know this isn't the right answer, but why?

You did something wrong with this part of the equation

(v/4)^2

I forgot to square the (1/4)! how silly of me.
Thank you!
