DETAILED EXPLANATION

\n" ); document.write( "
Look at \"highlight_red%28+2%2Ax%5E4%2Bx%5E2-3+%29=0\".
Equation \"highlight_red%28+2%2Ax%5E4%2Bx%5E2-3=0+%29\" is a quadratic equation, if we substitute \"Z=x%5E2\": and has solutions Z= 1 and solution \"x=root%28+2%2C+Z+%29\": 1,-1
It becomes \"highlight_green%28+0+%29=0\".
Result: \"0=0\"
