You can put this solution on YOUR website!
3x2 + 2x = 7
\n" ); document.write( "3x^2+2x-7 = 0
\n" ); document.write( "x = [-2 +- sqrt(4-4*3*-7)]/6
\n" ); document.write( "x = [-2 +- sqrt(89)]/6
\n" ); document.write( "x = [-2 + sqrt(89)]/6
\n" ); document.write( "x = [-2 - sqrt(89)]/6
\n" ); document.write( "-------------------------\r
\n" ); document.write( "\n" ); document.write( "x^2 + 8x + 9 = -7
\n" ); document.write( "x^2+8x+16=0
\n" ); document.write( "(x+4)^2 = 0
\n" ); document.write( "x = -4 with multiplicity 2
\n" ); document.write( "========================
