Best ResponseYou've already chosen the best response.1there is an alternative way:\[\begin{align} 2x^33x+1&=x(2x^23)+1\\ &=x(2x^23)(2x^23)+(2x^23)+1\\ &=(x1)(2x^23)+2x^23+1\\ &=(x1)(2x^23)+2x^22\\ &=(x1)(2x^23)+2(x^21)\\ &=(x1)(2x^23)+2(x1)(x+1)\\ &=(x1)(2x^23+2(x+1))\\ &=(x1)(2x^23+2x+2)\\ &=(x1)(2x^2+2x1) \end{align}\]
