I can say:
\n" ); document.write( "\"+f%28x%29+=+-2x%5E2+%2B+12x+-+10+\"
\n" ); document.write( "Then set \"+f%28x%29+=+0+\" to find the roots, or
\n" ); document.write( "x-intercepts
\n" ); document.write( "\"+-2x%5E2+%2B+12x+-+10+=+0+\"
\n" ); document.write( "Divide both sides by \"+2+\"
\n" ); document.write( "\"+-x%5E2+%2B+6x+-+5+=+0+\"
\n" ); document.write( "I can find roots with quadratic formula
\n" ); document.write( "\"+x+=+%28-b+%2B-+sqrt%28+b%5E2+-+4%2Aa%2Ac+%29%29+%2F+%282%2Aa%29+\"
\n" ); document.write( "\"+a+=+-1+\"
\n" ); document.write( "\"+b+=+6+\"
\n" ); document.write( "\"+c+=+-5+\"
\n" ); document.write( "\"+x+=+%28-6+%2B-+sqrt%28+6%5E2+-+4%2A%28-1%29%2A%28-5%29+%29%29+%2F+%282%2A%28-1%29%29+\"
\n" ); document.write( "\"+x+=+%28-6+%2B-+sqrt%28+36+-+20+%29%29+%2F+%28-2%29%29+\"
\n" ); document.write( "\"+x+=+%28-6+%2B-+sqrt%28+16+%29%29+%2F+%28-2%29%29+\"
\n" ); document.write( "\"+x+=+%28+-6+%2B+4+%29+%2F+%28-2%29+\"
\n" ); document.write( "\"+x+=+1+\"
\n" ); document.write( "and, also,
\n" ); document.write( "\"+x+=+%28+-6+-+4+%29+%2F+%28-2%29+\"
\n" ); document.write( "\"+x+=+5+\"
\n" ); document.write( "-----------
\n" ); document.write( "The x-intercepts are at \"+x+=+1+\" and \"+x+=+5+\"
\n" ); document.write( "Here's the plot:
