Question

Written as a simplified polynomial in standard form, what is the result when (2x-5)^2(2x−5)

2
is subtracted from x-10x−10?

Answer 1

-4x^2 +21x -35

Explanation:

The difference of the two polynomials is ...

(x -10) -(2x -5)^2

= (x -10) -(4x^2 -20x +25)

= x -10 -4x^2 +20x -25

= -4x^2 +21x -35
