What is a simpler form of the following expressions?

(7p - 8) (7p + 8)

A. 49p^2 + 112p + 64

B. 49p^2 - 112p - 64

C. 49p^2 + 64

D. 49p^2 - 64

D. 49p² - 64

Step-by-step explanation:

(7p - 8) (7p + 8)

Solving this requires the 'difference of squares' concept which states;

If (a - b) (a + b)

Then the solution must be a² - b²

Considering (7p - 8) (7p + 8) then the answer is;

(7p) ² - 8² = 49p² - 64
