Step-by-step explanation:
Use the quadratic formula
x=\frac{-\textcolor{#F28B82}{b}\pm \sqrt{\textcolor{#F28B82}{b}^{2}-4\textcolor{#C58AF9}{a}\textcolor{#8AB4F8}{c}}}{2\textcolor{#C58AF9}{a}}
Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.
x^{2}-2x+1=0
a=\textcolor{#C58AF9}{1}
b=\textcolor{#F28B82}{-2}
c=\textcolor{#8AB4F8}{1}
