You can put this solution on YOUR website!
3x^2 + 2x + 1 = 0
\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=[-2 +- sqrt(4 - 4(3)(1))]/2(3)
\n" ); document.write( "x=[-2 +- sqrt(4 - 4(3)(1))]/2(3)
\n" ); document.write( "x=[-2 +- sqrt(4 - 12)]/6
\n" ); document.write( "x=[-2 +- sqrt(-8)]/6
\n" ); document.write( "

\n" ); document.write( "Now the discriminant is less than zero (-8). Therefore there are no real solutions,both will be imaginary.
\n" ); document.write( "

\n" ); document.write( "square root of -8 = +- 2.8284271247461900976033774484194
\n" ); document.write( "

\n" ); document.write( "x=[-2 +- i(2.8284271247461900976033774484194)]/6
\n" ); document.write( "
