Question

combine like terms.
1 + 1 + 7x² + 7y³ + 3 + 2x² - y³

Explanation:

Step1: Identify constant terms

Constants: \(1, 1, 3\). Sum them: \(1 + 1 + 3 = 5\)

Step2: Identify \(x^2\) terms

\(x^2\) terms: \(7x^2, 2x^2\). Sum: \(7x^2 + 2x^2 = 9x^2\)

Step3: Identify \(y^3\) terms

\(y^3\) terms: \(7y^3, -y^3\). Sum: \(7y^3 - y^3 = 6y^3\)

Step4: Combine all results

Combine the sums: \(5 + 9x^2 + 6y^3\)

Answer:

\(9x^2 + 6y^3 + 5\)
