Question

Which polynomial represents the area of the shaded region with the fewest terms?​

Answer 1

14x-85

Explanation:

The area of the shaded region is

`(x + 6)(x - 6) - {(x - 7)}^(2)`

which if you use the identities to expand it gives you

`{x}^(2) - 36 - {x}^(2) + 14x - 49`

This then reduces to be

`14x - 85`
