[tex](4x^4+7x^3+15x^2+4)+(4x^3+2x^2+17x)[/tex]
We see that [tex]7x^3[/tex] and [tex]4x^3[/tex] has the same x variable, so we can add them to get [tex]11x^{3}[/tex].
Also, we can do the same to [tex]15x^2[/tex] and [tex]2x^2[/tex] to get [tex]17x^2[/tex].
Therefore, our answer is D) [tex]4x^4+11x^3+17x^2+17x+4[/tex]
