Vol = 50x^3 -2x +75x^2 -3
\n" ); document.write( ".
\n" ); document.write( "looking for V = L * W * H
\n" ); document.write( ".
\n" ); document.write( "factor original eqn
\n" ); document.write( ".
\n" ); document.write( "2x(25x^2 -1) +3(25x^2-1)
\n" ); document.write( ".
\n" ); document.write( "(2x+3)( 25x^2 -1)
\n" ); document.write( ".
\n" ); document.write( "(2x+3) (5x+1)(5x-1),,,,,sides of box
\n" ); document.write( ".
\n" ); document.write( "2x+3 =0,,,,,x=-1.5
\n" ); document.write( ".
\n" ); document.write( "5x +1 = 0,,,,,x= -1/5
\n" ); document.write( ".
\n" ); document.write( "5x-1=0,,,,,,x= 1/5
\n" ); document.write( ".
\n" ); document.write( "Smallest zero is (-1.5),, therefore x> -1.5
\n" ); document.write( "
\n" );
