two numbers whos sum is 11 and product is -60?\r
\n" ); document.write( "\n" ); document.write( "Let x and y be the two numbers. Then we have:\r
\n" ); document.write( "\n" ); document.write( "1.) x + y = 11
\n" ); document.write( "2.) x*y = -60\r
\n" ); document.write( "\n" ); document.write( "From 1.) we have x = 11 - y. Substitute 11-y for x in 2.):\r
\n" ); document.write( "\n" ); document.write( "(11-y)*y = -60
\n" ); document.write( "11y - y^2 = -60
\n" ); document.write( "y^2 - 11y - 60 = 0
\n" ); document.write( "(y-15)*(y+4) = 0\r
\n" ); document.write( "\n" ); document.write( "y=15 or y=-4\r
\n" ); document.write( "\n" ); document.write( "Find the corresponding values of x using x = 11-y. \r
