Question

use the grouping method to express the polynomial below as a product of its factors. write each factor as a polynomial in descending order x(10x-9)+11(10x-9)

Answer 1

Express the polynomial given as a product of its factors;

`\begin{gathered} x(10x-9)+11(10x-9) \\ =(x+11)(10x-9) \end{gathered}`

The commonn factor is

`(10x-9)`

Factor this out and you'll be left with

`x+11`
