Algebra.Com's Answer #97324 by nycsharkman(136) ![]() You can put this solution on YOUR website! Are you trying to simplify this radical?\r \n" ); document.write( "\n" ); document.write( "I will assume that you are trying to simplify it.\r \n" ); document.write( "\n" ); document.write( "sqrt{(a + 4)^2}\r \n" ); document.write( "\n" ); document.write( "The inside of the radical becomes a^2 + 8a + 16 after applying the FOIL method.\r \n" ); document.write( "\n" ); document.write( "We now house every term SEPARATELY in a radical and simplify.\r \n" ); document.write( "\n" ); document.write( "sqrt{a^2} = a\r \n" ); document.write( "\n" ); document.write( "sqrt{8a} = 2(sqrt{2a})\r \n" ); document.write( "\n" ); document.write( "sqrt{16} = 4\r \n" ); document.write( "\n" ); document.write( "We now have this:\r \n" ); document.write( "\n" ); document.write( "a times 2 times 4 times sqrt{2a} =\r \n" ); document.write( "\n" ); document.write( "8a(sqrt{2a})\r \n" ); document.write( "\n" ); document.write( "Did you follow?\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
