$\"%28x%2By%29%282x-1%29%28x%2B1%29\"$ . First of all, you must multiply first two polynomials, $\"%28x%2By%29%282x-1%29\"$ . Use the distributive property: $\"x%282x-1%29+%2By%282x-1%29\"$ the reason is because you could use distributive property even if these two are polynomials. So,it would be, $\"x+%2A+2x+-+x+%2A+1+%2B+y+%2A+2x+-+y+%2A+1\"$ and just simplify the like terms. But we are not done yet. after we combine it, which is $\"2x%5E2+-+x+%2B+2xy+-+y\"$ , we also have to multiply $\"%28x%2B1%29\"$ as well, remember? We should rather use polynomials ( the $\"x%2B1%29\"$ ) than quadnomials ( the $\"2x%5E2+-+x+%2B+2xy+-+y\"$ ) to use as distributive property, so this is what it should be: $\"+x%282x%5E2+-+x+%2B+2xy+-+y%29+%2B+1%282x%5E2+-+x+%2B+2xy+-+y%29+\"$ which simplify all the way down to: $\"+2x%5E3+-+x%5E2+%2B+2x%5E2y+-+xy+%2B+2x%5E2+-+x+%2B+2xy+-+y\"$ then to: $\"+2x%5E3+%2B+x%5E2+%2B+2x%5E2y+%2B+xy+-+x+-+y\"$ .

. So it would be $\"1%281%2B1%29%2B1%281%2B1%29\"$ . i hope you aren't still confused... \n" ); document.write( "
