To add the polynomials, combine like terms: $2x^5 + 9x^5 = 11x^5$, $-2x^4 - 8x^4 = -10x^4$, $9x^3 + 9x^3 = 18x^3$, and $3 + 1 = 4$.

Perform the Indicated Operation (2x5−2x4+9x3+3)+(9x5−8x4+9x3+1)\left( 2 x ^ { 5 } - 2 x ^ { 4 } + 9 x ^ { 3 } + 3 \right) + \left( 9 x ^ { 5 } - 8 x ^ { 4 } + 9 x ^ { 3 } + 1 \right)(2x5−2x4+9x3+3)+(9x5−8x4+9x3+1)

Perform the Indicated Operation $\left( 2 x ^ { 5 } - 2 x ^ { 4 } + 9 x ^ { 3 } + 3 \right) + \left( 9 x ^ { 5 } - 8 x ^ { 4 } + 9 x ^ { 3 } + 1 \right)$
