Use the method of completing the square to find the standard form of the quadratic function.
\n" ); document.write( "f(x) = x^2 + 6x − 1
\n" ); document.write( " = x^2 + 6x-1=0
\n" ); document.write( " x^2 +6x=1
\n" ); document.write( "x^2+6x+9=1+9
\n" ); document.write( "(x+3)^2=10
\n" ); document.write( "(x+3=±√10
\n" ); document.write( "x=-3±√10\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
