Algebra.Com's Answer #655542 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! x, x+2, x+4 are integers \n" ); document.write( "2x(x+2)-16=(x+2)(x+4). Twice the product of the first minus 16 will be the product of the second. \n" ); document.write( "2x^2+4x=x^2+6x+8, expanding. \n" ); document.write( "x^2-2x-24=0, collecting terms \n" ); document.write( "(x-6)(x+4)=0 \n" ); document.write( "x=6,-4 are possibilities \n" ); document.write( "6,8,10 and -4,-2,0 \n" ); document.write( "2(6*8)=96 \n" ); document.write( "8*10=80, and add 16 get 96. \n" ); document.write( "So 6,8,10 are the integers \n" ); document.write( "check -4,-2,0 \n" ); document.write( "2(-4*-2)=16 \n" ); document.write( "That is 16 more than the product of -2*0 \n" ); document.write( "so -4,-2, and 0 are also possible. \n" ); document.write( " |
