Question

What is the sum of the polynomials 3db + 2ab2 and -ab² + a²6² ? A. - B. 3a²b - ab? + 3a²b2 3a²b ab2 + 2a²b2 2a²b 2a²b3 + 2a464 -30°13 + 2a4b C. D. E. + 3a²b2

Answer 1

To determine the sum of the polynomials

`\begin{gathered} 3a^2b+2a^2b^2,-ab^2+a^2b^2 \\ \\ \end{gathered}`
`\begin{gathered} 3a^2b+2a^2b^2+\text{ -}ab^2+a^2b^2 \\ 3a^2b+2a^2b^2-\text{ }ab^2+a^2b^2 \\ \text{collect like terms} \\ 3a^2b-ab^2+2a^2b^2+a^2b^2 \\ 3a^2b-ab^2+3a^2b^2 \end{gathered}`

Hence the correct answer is Option A
