Question

Written as a simplified polynomial in standard form, what is the result when

(3x – 2)2 is subtracted from 9?

Answer 1

-9x^2 + 12x + 5

Explanation:

I'm assuming you meant (3x – 2)^2. The " ^ " indicates exponentiation and is required. We then have:

9 - (3x – 2)^2, which, when expanded, is

9 - (9x^2 -12x + 4), or:

-9x^2 + 12x + 5
