\\(6x^8 - 7x^3 + 2x^2\\)
\\(-3x^8 + 5x^3 - 8x^2\\)
\\(-8x^8 - 2x^3 - 5x^2\\)
\\(-5x^8 - 4x^3 - 11x^2\\)

Explanation:

Step1: Add \(x^8\) terms

\(6x^8 - 3x^8 - 8x^8=(6 - 3 - 8)x^8=-5x^8\)

Step2: Add \(x^3\) terms

\(-7x^3 + 5x^3 - 2x^3=(-7 + 5 - 2)x^3=-4x^3\)

Step3: Add \(x^2\) terms

\(2x^2 - 8x^2 - 5x^2=(2 - 8 - 5)x^2=-11x^2\)

Step4: Combine results

Combine the results from Step1, Step2 and Step3: \(-5x^8-4x^3 - 11x^2\)

Answer:

\(-5x^8-4x^3 - 11x^2\)
