$\"%28x%2B9%29%5E2+=+20\"$
\n" ); document.write( " $\"x%2B9=sqrt%2820%29\"$ , or $\"x%2B9=-sqrt%2820%29\"$
\n" ); document.write( " $\"x%5B1%5D=-9%2Bsqrt%2820%29\"$ , $\"x%5B2%5D=-9-sqrt%2820%29\"$ the exact solutions\r
\n" ); document.write( "\n" ); document.write( " $\"x%5B1%5D=-4.528\"$ , $\"x%5B2%5D=-13.472%29\"$ the approximate solutions to three decimal places \n" ); document.write( "
