Let the two numbers be represented by x and y
\n" ); document.write( "You are told \" When they are multiplied, the product is 36, when they are added, the sum is 15, what are the two numbers?\"
\n" ); document.write( "So
\n" ); document.write( "\"x+%2A+y+=+36\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x+%2B+y+=+15\" isolate x
\n" ); document.write( "\"x+=+15-y\" use this value for x in the first equation\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x+%2A+y+=+36\"
\n" ); document.write( "\"%2815-y%29%2Ay+=+36\" expand
\n" ); document.write( "\"15y+-+y%5E2+=+36\" collect into quadratic form
\n" ); document.write( "\"0+=+y%5E2+-15y+%2B36\" factor
\n" ); document.write( "\"0+=+%28y-3%29%28y-12%29\" For a product to be zero,one or more factors must be 0
\n" ); document.write( "So
\n" ); document.write( "\"y-3=0\" or \"y-12=0\"
\n" ); document.write( "y = 3 or y = 12\r
\n" ); document.write( "\n" ); document.write( "The two numbers are 3 and 12\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
