solve the inequality. Graph the solution set and write it in interval notation.
\n" ); document.write( "x^2-4x+13<0
\n" ); document.write( "completing the square
\n" ); document.write( "y=(x^2-4x+4)+13-4
\n" ); document.write( "y=(x-2)^2+9
\n" ); document.write( "This is a parabola which opens upwards with a minimum=9\r
\n" ); document.write( "\n" ); document.write( "Therefore, there is no solution to given expression which cannot<0
\n" ); document.write( "
\n" );
