You can put this solution on YOUR website!
4x^2+2x+7>=14x^2-4x
\n" ); document.write( "---------
\n" ); document.write( "10x^2-6x-7 <= 0
\n" ); document.write( "-----------
\n" ); document.write( "Solve the EQUALITY:
\n" ); document.write( "x = [6 +- sqrt(36 -4*10*-7)]/20\r
\n" ); document.write( "\n" ); document.write( "x= [6 +- sqrt(316)]/20\r
\n" ); document.write( "\n" ); document.write( "x = [6 +- 17.7764]20\r
\n" ); document.write( "\n" ); document.write( "x = 1.1888 or x = -0.5888
\n" ); document.write( "------------------------------
\n" ); document.write( "The parabola opens upward so the interval where 10x^2-6x-7
\n" ); document.write( "is less than zero is -0.5888 < x < 1.1888
\n" ); document.write( "---------------------------------------------
\n" ); document.write( "Final solution: -0.5888 <= x <= 1.1888
\n" ); document.write( "=========================================
