Answer:
![(2x-1)^2](https://tex.z-dn.net/?f=%282x-1%29%5E2)
Step-by-step explanation:
![4x^2-4x+1=\\(2x)^2+2(2x)(-1)+(-1)^2\\\\\textrm{Using the rule }A^2+2AB+B^2=(A+B)^2\textrm{, then:}\\(2x)^2+2(2x)(-1)+(-1)^2=(2x-1)^2](https://tex.z-dn.net/?f=4x%5E2-4x%2B1%3D%5C%5C%282x%29%5E2%2B2%282x%29%28-1%29%2B%28-1%29%5E2%5C%5C%5C%5C%5Ctextrm%7BUsing%20the%20rule%20%7DA%5E2%2B2AB%2BB%5E2%3D%28A%2BB%29%5E2%5Ctextrm%7B%2C%20then%3A%7D%5C%5C%282x%29%5E2%2B2%282x%29%28-1%29%2B%28-1%29%5E2%3D%282x-1%29%5E2)
3m-4n=1
3m-2n=-1
I wouldn't graph because I'm lazy
I wouldn't subsitute because I'm too lazy to put it into a form m=something or n=something
i would eliminate because the m's are both 3, just multiply the top equaiton by -1 and add them equations to get 2n=-2, so n=-1,then m=-1 so then (-1,-1) is solution
eliminate
