Question 1071221
How to "solve" the function?

Solve?



{{{f(x)=2x^2-8x+2}}}
{{{highlight_green(2(x^2-4x+1))}}}



But if you wanted to go further,  {{{(-4/2)^2=4}}}, a term for "completing the square".


{{{2(x^2-4x+4+1-4)}}}
{{{2((x^2-4x+4)+1-4)}}}
{{{2((x-2)^2-3)}}}
{{{highlight_green(f(x)=2(x-2)^2-6)}}}
