Here is the original equation:
\n" ); document.write( "(i) $\"r%5E2-10=3r\"$
\n" ); document.write( "step 1 - set = 0.
\n" ); document.write( "(ii) $\"r%5E2-3r+-+10+=+0\"$
\n" ); document.write( "step 2 - factor to get
\n" ); document.write( "(iii) $\"%28r-5%29%28r%2B2%29=0\"$
\n" ); document.write( "step 3 solve each parenthesis for r to get
\n" ); document.write( "r-5 = 0
\n" ); document.write( "r = 5
\n" ); document.write( "r+2 = 0
\n" ); document.write( "r = -2 \n" ); document.write( "

\n" );
