x+y=27
\n" ); document.write( "y=27-x
\n" ); document.write( "xy=152
\n" ); document.write( "x(27-x)=152
\n" ); document.write( "\"-x%5E2%2B27x=152\"
\n" ); document.write( "\"-x%5E2%2B27x-152=0\"
\n" ); document.write( "Use Quadratic formula: \"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"
\n" ); document.write( "a= -1, b=27, c=-152
\n" ); document.write( "\"x+=+%28-27+%2B-+sqrt%28+27%5E2-4%28-1%29%28-152%29+%29%29%2F2%28-1%29%29+\"
\n" ); document.write( "\"x+=+%28-27+%2B-+sqrt%28+729-608%29%29%2F-2%29\"
\n" ); document.write( "\"x+=+%28-27+%2B-+sqrt%28121%29%29%2F-2%29\"
\n" ); document.write( "Add: \"x+=+%28-27+%2B+11%2F-2%29\"
\n" ); document.write( "x=8
\n" ); document.write( "27-8 = 19
\n" ); document.write( "Hence, the two numbers are 8 and 19.
