$\"x%5E2-8x%2B3=0\"$
\n" ); document.write( " $\"x%5E2-8x=-3\"$
\n" ); document.write( " $\"x%5E2-8x%2B16=-3%2B16\"$
\n" ); document.write( " $\"x%5E2-8x%2B16=13\"$
\n" ); document.write( " $\"%28x-4%29%5E2=13\"$
\n" ); document.write( "We can write the last equation like this:
\n" ); document.write( " $\"%28x-4%29=sqrt%2813%29\"$
\n" ); document.write( " $\"x=4%2Bsqrt%2813%29\"$
\n" ); document.write( "or
\n" ); document.write( " $\"%28x-4%29=-sqrt%2813%29\"$
\n" ); document.write( " $\"x=4-sqrt%2813%29\"$ \r
\n" ); document.write( "\n" ); document.write( "So, solutions for this quadratic equations are:
\n" ); document.write( " $\"x=4%2Bsqrt%2813%29\"$ or $\"x=4-sqrt%2813%29\"$ \r
\n" ); document.write( "\n" ); document.write( "OK \n" ); document.write( "
