Question

Quizplus · Accepted Answer

To add the polynomials, combine like terms: $(-6x^5 + 8x^5) + (18x^3 + 4x^3) + (15 - 11) = 2x^5 + 22x^3 + 4$.

Perform the Indicated Operations (−6x5+18x3+15)+(8x5+4x3−11)\left( - 6 x ^ { 5 } + 18 x ^ { 3 } + 15 \right) + \left( 8 x ^ { 5 } + 4 x ^ { 3 } - 11 \right)(−6x5+18x3+15)+(8x5+4x3−11)
