solve
\n" ); document.write( "x^4 + 3x^3 -10x^2 = 0
\n" ); document.write( ".
\n" ); document.write( "Begin by factoring out x^2:
\n" ); document.write( "x^2(x^2 + 3x -10) = 0
\n" ); document.write( ".
\n" ); document.write( "Now, factor expression inside parenthesis:
\n" ); document.write( "x^2(x+5)(x-2) = 0
\n" ); document.write( "setting each term on the left to zero we get:
\n" ); document.write( "x = {-5, 0, 2} \n" ); document.write( "

\n" );
