\left(-x+1\right)^{2}
Combine x and -2x to get -x.
x^{2}-2x+1
Use binomial theorem \left(a+b\right)^{2}=a^{2}+2ab+b^{2} to expand \left(-x+1\right)^{2}.
\left(-x+1\right)^{2}
Combine x and -2x to get -x.
x^{2}-2x+1
Use binomial theorem \left(a+b\right)^{2}=a^{2}+2ab+b^{2} to expand \left(-x+1\right)^{2}.
