$\"+3x%5E2+-+4x+%2B+%28+k%2B1+%29+=+0+\"$
\n" ); document.write( "using qudratic formula, the 2 roots make

\n" ); document.write( "

\n" ); document.write( " $\"+%28+4+%2B+sqrt%28+16-12c+%29%29%2F6+=+2%2A%28+%28+4+-+sqrt%28+16-12c+%29%29%2F6+%29+%2B+1+\"$
\n" ); document.write( "Multiply both sides by $\"+6+\"$
