You can put this solution on YOUR website!
Let the numbers be x and x+1
\n" ); document.write( "Then x(x+1) = 72
\n" ); document.write( "==> x^2 + x - 72 = 0
\n" ); document.write( "==> x^2 + 9x - 8x - 72 = 0
\n" ); document.write( "==> x(x+9) - 8(x+9) = 0
\n" ); document.write( "==> (x+9) (x - 8) = 0
\n" ); document.write( "==> x + 9 = 0 or x - 8 = 0
\n" ); document.write( "==> x = -9 or x = 8
\n" ); document.write( "Thus the numbers are -9, -8 or 8, 9\r
