You can put this solution on YOUR website!
x(3x + 1) (x + 1) = 0
\n" ); document.write( "You need to find x so that the equation equals zero.
\n" ); document.write( "There are three cases when the equation will equal zero, that is, when the three individual expressions equal zero.
\n" ); document.write( "1.x=0
\n" ); document.write( "2.3x+1=0
\n" ); document.write( "3.x+1=0
\n" ); document.write( "The first solution is x=0.
\n" ); document.write( "The second solution requires some manipulating.
\n" ); document.write( "3x+1=0
\n" ); document.write( "3x=-1
\n" ); document.write( "x=-1/3.
\n" ); document.write( "The second solution is x=-1/3.
\n" ); document.write( "The third solution is found similarly.
\n" ); document.write( "x+1=0
\n" ); document.write( "x=-1
\n" ); document.write( "The third solution is x=-1. \n" ); document.write( "

\n" );
