Pr=x^{2}-2xa+a^{2}
Use binomial theorem \left(p-q\right)^{2}=p^{2}-2pq+q^{2} to expand \left(x-a\right)^{2}.
rP=x^{2}-2ax+a^{2}
The equation is in standard form.
\frac{rP}{r}=\frac{\left(x-a\right)^{2}}{r}
Divide both sides by r.
P=\frac{\left(x-a\right)^{2}}{r}
Dividing by r undoes the multiplication by r.
