A positive integer is 11 more than 5 times another. The product is 988. Find the two integers using the quadratic formula.
\n" ); document.write( "..
\n" ); document.write( "let one number be x
\n" ); document.write( "other number is 11 more than 5x = 5x+11
\n" ); document.write( "..
\n" ); document.write( "product = 988
\n" ); document.write( "x(5x+11)=988
\n" ); document.write( "5x^2+11x=988
\n" ); document.write( "5x^2+11x-988=0
\n" ); document.write( "..
\n" ); document.write( "solve for roots x1 & x2
