Algebra.Com's Answer #31798 by stanbon(75887) ![]() You can put this solution on YOUR website! You are missing x=0. \n" ); document.write( "So the number line is broken at -1,0, and 4. \n" ); document.write( "Check the 4 resulting intervals to see where your solutions lie. \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
