Algebra.Com's Answer #67620 by vertciel(183)![]() ![]() ![]() You can put this solution on YOUR website! Similarly with second-degree terms, you can just foil out (x + y)^3:\r \n" ); document.write( "\n" ); document.write( "= (x + y)(x + y)(x + y)\r \n" ); document.write( "\n" ); document.write( "= x^2 + 2xy + y^2(x + y)\r \n" ); document.write( "\n" ); document.write( "= You try to solve it.\r \n" ); document.write( "\n" ); document.write( "Alternatively, you could use the Binomial Theorem. \n" ); document.write( " |
