Question

write the polynomial in standard form.\\((-2x^{3}+7x^{2}-10x + 3)+(9x^{3}+4x^{2}-8x-7)=\square\\)

Explanation:

Step1: Combine like terms for \(x^3\)

\(-2x^3 + 9x^3 = 7x^3\)

Step2: Combine like terms for \(x^2\)

\(7x^2 + 4x^2 = 11x^2\)

Step3: Combine like terms for \(x\)

\(-10x - 8x = -18x\)

Step4: Combine constant terms

\(3 - 7 = -4\)

Step5: Write in standard form

Combine all the combined terms: \(7x^3 + 11x^2 - 18x - 4\)

Answer:

\(7x^3 + 11x^2 - 18x - 4\)
