You can put this solution on YOUR website!
If you multiply both sides by \"x%2A%28x-5%29\", the
\n" ); document.write( "equation will still be true
\n" ); document.write( "\"4x%2F%28x-5%29+%2B+2%2Fx++=+-4%2F%28x-5%29\"
\n" ); document.write( "
\n" ); document.write( "\"x%2A4x+%2B+2%2A%28x-5%29+=+-4x\"
\n" ); document.write( "\"4x%5E2+%2B+2x+-+10+=+-4x\"
\n" ); document.write( "\"4x%5E2+%2B+6x+-+10=+0\"
\n" ); document.write( "\"2x%5E2+%2B+3x+-+5+=+0\"
\n" ); document.write( "Use the quadratic formula to solve
\n" ); document.write( "\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"
\n" ); document.write( "\"a+=+2\"
\n" ); document.write( "\"b+=+3\"
\n" ); document.write( "\"c+=+-5\"
\n" ); document.write( "\"x+=+%28-3+%2B-+sqrt%28+3%5E2-4%2A2%2A%28-5%29+%29%29%2F%282%2A2%29+\"
\n" ); document.write( "\"x+=+%28-3+%2B-+sqrt%28+9+%2B+40+%29%29%2F4+\"
\n" ); document.write( "\"x+=+%28-3+%2B-+sqrt%28+49+%29%29%2F4+\"
\n" ); document.write( "\"x+=+%28-3+%2B+7%29%2F4\"
\n" ); document.write( "\"x+=+1\"
\n" ); document.write( "and
\n" ); document.write( "\"x+=+%28-3+-+7%29%2F4\"
\n" ); document.write( "\"x+=+-5%2F2\"
