Answer
(k+8)(k-8)
Work Step by Step
We use the formula for the difference of squares to apply to this question.
The difference of squares formula is:
$(a-b) (a+b) = a^{2} - b^{2}$
= $(k)^{2}$ - 64 *** Take the square root of 64 which is 8. Becuase 8 × 8= 64
= $(k)^{2}−8^{2}$
In the given formula let k represents a and 8 represents b.
$(k)^{2}−8^{2}$ = (k+8)(k-8)
