Question

Add polynomials (p^2 -6p -18) + ( 2p^2 + 11)

Answer 1

Given:

`(p^2-6p-18)+(2p^2+11)`

To add the polynomial,

step 1: Open parentheses

`p^2-6p-18+2p^2+11`

step 2: Collect like terms.

`\begin{gathered} p^2-6p-18+2p^2+11 \\ \Rightarrow p^2+2p^2-6p-18+11 \\ =3p^2-6p-7 \end{gathered}`

Hence, we have

`3p^2-6p-7`
