Answer:

The answer is (8x²- 25x +7).

Step-by-step explanation:

Given A, B, C are the polynomials.

A = 3x - 4

B = x + 7

C = x² + 2

We have to find the value of A²-(B + C)

By putting the values of A, B and C the expression will be

(3x - 4)²- (x + 7 + x² + 2) = (9x²+16-24x) - (x² + x + 9)

9x² - x² -24x - x + 16 - 9 = 8x² - 25x + 7

So the simplest form of the expression is (8x² - 25x + 7)
