Instead of plugging in
and
right away, notice that
![m^2-2mn+n^2=(m-n)^2](https://tex.z-dn.net/?f=m%5E2-2mn%2Bn%5E2%3D%28m-n%29%5E2)
and now evaluating this expression at the two given values is easier, if only a little:
![((-2)-4)^2=(-6)^2=(-1)^2\times6^2=1\times36=36](https://tex.z-dn.net/?f=%28%28-2%29-4%29%5E2%3D%28-6%29%5E2%3D%28-1%29%5E2%5Ctimes6%5E2%3D1%5Ctimes36%3D36)
Answer:
you have to draw a triangle and 1200 is the straight leg on the right triangle. then the line on the bottom is the 5000 and you solve with the Pathagorian theorem
