Answer
$(5x+6)(5x-6)$
Work Step by Step
We use the formula for the difference of squares to apply to this question.
The difference of squares formula is:
$(a-b) (a+b) = a^{2} - b^{2}$
= $25x^{2}$ - 36
*** Take the square root of $25x^{2}$ which is 5x. Becuase 5x × 5x= $25x^{2}$
*** Take the square root of 36 which is 6. Becuase 6 × 6= 36
= $(5x)^{2}−6^{2}$
In the given formula let 5x represents a and 6 represents b.
$(5x)^{2}−6^{2}$= (5x+6)(5x-6)
