Algebra.Com's Answer #44537 by stanbon(75887) ![]() You can put this solution on YOUR website! f(x)= -6x^5+x^4+5x^3+x+1 \n" ); document.write( "# of changes in signs = 1 \n" ); document.write( "Therefore one positive real zero. \n" ); document.write( "-------------- \n" ); document.write( "f(-x)=6x^+x^4-5x^3-x+1 \n" ); document.write( "# of changes in signs = 2 \n" ); document.write( "Therefore 2 or 0 negative real zeroes. \n" ); document.write( "----------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
