Algebra.Com's Answer #498619 by LinnW(1048)![]() ![]() You can put this solution on YOUR website! x^2(x-16)(x-4) = 0 \n" ); document.write( "we want values of x so the left hand side = 0 \n" ); document.write( "So we need to solve \n" ); document.write( "x^2 = 0 \n" ); document.write( "x-16 = 0 \n" ); document.write( "and \n" ); document.write( "x-4 = 0\r \n" ); document.write( "\n" ); document.write( "Take x^2 = 0 \n" ); document.write( " x = 0 is the solution here. \n" ); document.write( "Take x-16 = 0 \n" ); document.write( " subtract 16 from each side \n" ); document.write( " x = 16 \n" ); document.write( "Take x-4 = 0 \n" ); document.write( " subtract 4 from each side \n" ); document.write( " x = 4\r \n" ); document.write( "\n" ); document.write( "so the possible values for x are 0, 16, and 4 \n" ); document.write( " |
