6x -2x3 + 10x+2x3+7x4 simply

zmey [24]

$(((6x-(2*(x3)))+10x)+(2*(x3)))+7x4 \\ \\ Then \ we \ simplify \ it \ down \ more. \\ \\ (((6x-(2*(x^3)))+10x)+2x^3)+7x^4 \\ \\ then \ we \ would \ then \ pull \ out \ the \ like \ factors . . . . \\ \\ 7x^4 + 16x = x * (7x^3 + 16) \\ \\$

Your final answer: $\boxed{\bf{ x *(7x^3 + 16)}}$
