Integral square error computation

Hi,
I am struggling computing the integral square error between two square waves. one is ideal and the other is assymetric.
the equation for the assymetric is:
x(t)=
A for |t|<=To/4+ε/2
and
-A for (To/4)+(ε/2)<|t|<=To/2

we were asked to plot the ideal( without the ε) and actual (or assymetric) waveforms and compute the integral square error between the two waveforms.

I only have the final solution which is 4εA^2. I cannot find it
Please can someone help me?

Thank you
B
