To add the given polynomials, combine like terms: $3x^6 + 5x^6 = 8x^6$, $5x^4 + 5x^4 = 10x^4$, and $-7 - 2 = -9$. This results in $8x^6 + 10x^4 - 9$.

Add - (−7+3x6+5x4)+(5x6+5x4−2)\left(-7+3 x^{6}+5 x^{4}\right)+\left(5 x^{6}+5 x^{4}-2\right)(−7+3x6+5x4)+(5x6+5x4−2) A) 8x6+10x4−98 x^{6}+10 x^{4}-98x6+10x4−9 B) 9x109 x^{10}9x10
