You can put this solution on YOUR website!
f(x)=3x-1+1/(x+1) = 0
\n" ); document.write( "Notice I added parentheses. You should do that.
\n" ); document.write( "3x-1+1/(x+1) = 0
\n" ); document.write( "Multiply thru by x+1
\n" ); document.write( "3x*(x+1) - (x+1) + 1 = 0
\n" ); document.write( "3x^2 + 2x = 0
\n" ); document.write( "x = 0
\n" ); document.write( "x = -2/3\r
\n" ); document.write( "\n" ); document.write( "
