Answer:
The correct answer option is: it is a difference of squares: (y – 15)(y + 15)
Explanation:
We are given a polynomial and we are to determine if it is a difference of squares.
Let us recall the algebraic formulas which include:



So if we look closely, we can conclude that the given polynomial observes the third formula of the perfect squares.
Hence, we can say that it is a difference of squares: (y – 15)(y + 15)
