It's a quadratic equation with mixed number coefficients.
\n" ); document.write( "First, make the mixed numbers into fractions.
\n" ); document.write( "\"6%2B2%2F3=20%2F3\"
\n" ); document.write( "\"1%2B1%2F3=4%2F3\"
\n" ); document.write( "\"-%2820%2F3%29x%5E2%2B%284%2F3%29x=2%2F3\"
\n" ); document.write( "Now multiply by -(3/2) to get rid of fractions and get to simplest form,
\n" ); document.write( "\"10x%5E2-2x=-1\"
\n" ); document.write( "\"10x%5E2-2x%2B1=0\"
\n" ); document.write( "Use the quadratic formula,
\n" ); document.write( "\"x+=+%282+%2B-+sqrt%28+2%5E2-4%2A10%2A1+%29%29%2F%282%2A10%29+\"
\n" ); document.write( "\"x+=+%282+%2B-+sqrt%28+4-40+%29%29%2F20+\"
\n" ); document.write( "\"x+=+%282+%2B-+sqrt%28+-36+%29%29%2F20+\"
\n" ); document.write( "\"x+=+%282+%2B-+6i%29%2F20+\"
\n" ); document.write( "\"highlight%28x+=+%281+%2B-+3i%29%2F10+%29\"
\n" ); document.write( "where \"i=sqrt%28-1%29\"
\n" ); document.write( "
\n" );
