\[x^2=3x-1\]\[x^2\color{red} {-3x+1}=3x-1\color{red} {-3x+1}\]\[x^2-3x+1=0\]

Answer 2

\[\huge\color{red}{\frac{-b±\sqrt{b^2-4ac}}{2a}}\]

Answer 3

\[\huge\color{red}{1}x^2\huge\color{red}{-3}x+\huge\color{red}{1}=0\]compare to
\[\huge\color{red}{a}x^2+\huge\color{red}{b}x+\huge\color{red}{c}=0\]Do you see your a b and c? PLUG THEM IN.
