Answer:

[tex]\large\boxed{(2x^4+x^3-4x^2+3)+(4x^4-2x^3-x^2+10x+2)=6x^4-x^3-5x^2+10x+5}[/tex]

Step-by-step explanation:

[tex](2x^4+x^3-4x^2+3)+(4x^4-2x^3-x^2+10x+2)\\\\=2x^4+x^3-4x^2+3+4x^4-2x^3-x^2+10x+2\qquad\text{combine like terms}\\\\=(2x^4+4x^4)+(x^3-2x^3)+(-4x^2-x^2)+10x+(3+2)\\\\=6x^4-x^3-5x^2+10x+5[/tex]
