\n" ); document.write( "b^2-4ac=0+900
\n" ); document.write( "b^2-4ac=900 : sqrt(900)=30
\n" ); document.write( " $\"x=%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F%282a%29\"$
\n" ); document.write( " $\"x1=%28-b%2Bsqrt%28b%5E2-4ac%29%29%2F%282a%29\"$
\n" ); document.write( "x1=(0+30)/6
\n" ); document.write( "x1=5
\n" ); document.write( "x2=(0-30)/6
\n" ); document.write( "x2= -5
