Algebra.Com's Answer #371257 by jim_thompson5910(35256) ![]() You can put this solution on YOUR website! (x+4)^2 =(x+4)(x+4) = x*x + 4x + 4x + 4*4 = x^2 + 4x + 4x + 16 = x^2 + 8x + 16\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So (x+4)^2 = x^2 + 8x + 16 for all values of x. \n" ); document.write( " |
