Algebra.Com's Answer #154364 by stanbon(75887) ![]() You can put this solution on YOUR website! List all real values of x such that f(x) = 0. If there are no such real x, type DNE. If there is more that one real x, give a comma separated list (i.e.: 1,2). \n" ); document.write( "f(x) = 19/(x -8) + (-18)/(x + 2) \n" ); document.write( "---- \n" ); document.write( "19/(x -8) + (-18)/(x + 2) = 0 \n" ); document.write( "--- \n" ); document.write( "Multiply thru by (x-8)(x+2) \n" ); document.write( "19(x+2) + -18(x-8) = 0 \n" ); document.write( "19x + 38 -18x + 144 = 0 \n" ); document.write( "x = -182 \n" ); document.write( "===================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
