Determine whether the polynomial is a difference of squares and if it is, factor it.y2 − 25
A. Is not a difference of squares
B. Is a difference of squares: (y − 5)2
C. Is a difference of squares: (y + 5)(y − 5)
D. Is a difference of squares: (y + 5)2

Answers

Answer:

Option: C is the correct answer.

C. Is a difference of squares: (y + 5)(y − 5).

Step-by-step explanation:

We are given a polynomial expression in terms of the variable y as follows:

$y^2-25$

Now this expression could also be written as:

$y^2-25=y^2-5^2$

This means that the expression is a difference of squares.

Also, we know that:

$a^2-b^2=(a+b)(a-b)$

Here,

$a=y\ and\ b=5$

Hence,

$y^2-25=(y+5)(y-5)$

the answer is C
y² - 25
= y² - 5²
= (y + 5)(y - 5) which is a difference of two squares
