In the quadratic formula, for repeated solutions
\n" ); document.write( "(1) \"+b%5E2+-+4%2Aa%2Ac+=+0+\"
\n" ); document.write( "and
\n" ); document.write( "(2) \"+x+=+-b%2F%28+2a+%29+\"
\n" ); document.write( "——————————-
\n" ); document.write( "\"+k%2Ax%5E2+%2B+x+%2B+100k+=+0+\"
\n" ); document.write( "\"+b+=+1+\"
\n" ); document.write( "\"+a+=+k+\"
\n" ); document.write( "\"+c+=+100k+\"
\n" ); document.write( "(1) \"+1%5E2+-+4%2Ak%2A100k+=+0+\"
\n" ); document.write( "(1) \"+1+-+400k%5E2+=+0+\"
\n" ); document.write( "(1) \"+k%5E2+=+1%2F400+\"
\n" ); document.write( "\"+k+=+1%2F20+\"
\n" ); document.write( "or
