Answer
(7p+2)(7p-2)
Work Step by Step
We use the formula for the difference of squares to apply to this question.
The difference of squares formula is:
$(a-b) (a+b) = a^{2} - b^{2}$
= $49p^{2}$ - 4
*** Take the square root of $49p^{2}$ which is 7p. Becuase 7p × 7p= $49p^{2}$
*** Take the square root of 4 which is 2. Becuase 2 × 2= 4
= $(7p)^{2}−2^{2}$
In the given formula let 7p represents a and 2 represents b.
$(7p)^{2}−2^{2}$ = (7p+2)(7p-2)
