Solve by factoring:
\n" ); document.write( " $\"x%5E2%2B3kx-10k%5E2+=+0\"$
\n" ); document.write( " $\"%28x-2k%29%28x%2B5k%29+=+0\"$ Apply the \"zero products principle\" (ab = 0, iff a = 0 and/or b=0)
\n" ); document.write( " $\"x-2k+=+0\"$ and/or $\"x%2B5k+=+0\"$
\n" ); document.write( "If $\"x-2k+=+0\"$ then $\"x+=+2k\"$
\n" ); document.write( "If $\"x%2B5k+=+0\"$ then $\"x+=+-5k\"$ \r
\n" ); document.write( "\n" ); document.write( "P.S. iff means \"if and only if\" \n" ); document.write( "

\n" );
