\n" ); document.write( "Hi
\n" ); document.write( "one of the integers is five less than seven times the other integer.
\n" ); document.write( "Let x and (7x-5)represent the intergers
\n" ); document.write( "Question states***
\n" ); document.write( " x(7x-5) = 408
\n" ); document.write( " 7x^2 - 5x -408 = 0
\n" ); document.write( "Solving for x\r
\n" ); document.write( "\n" ); document.write( "\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"
\n" ); document.write( "\"x+=+%285+%2B-+sqrt%28+11449%29%29%2F%2814%29+\"
\n" ); document.write( "\"x+=+%285+%2B-+107%29%2F14\"
\n" ); document.write( " x = 112/14 = 8 and x = -102/14 (extraneous solution as is a non-integer)
\n" ); document.write( "Integers are 8 and 51 (7*8-5)\r
