Choose values of x to show that 2x^2-32/x-4 does not simplify to 2x-8. \n" ); document.write( "------ \n" ); document.write( "Assume [2x^2-32/x-4] = [2x-8] \n" ); document.write( "Test x = 0 \n" ); document.write( "You get [(0-32)/(0-4)] = [0-8] \n" ); document.write( "or [-32/-4] = [-8] \n" ); document.write( "or 8 = -8 , which is wrong. \n" ); document.write( "---------------------------- \n" ); document.write( "This shows that the assumed equality is not true. \n" ); document.write( "======================================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
