the answer is C
y² - 25
= y² - 5²
= (y + 5)(y - 5) which is a difference of two squares
y² - 25
= y² - 5²
= (y + 5)(y - 5) which is a difference of two squares
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:
[tex]y^2-25[/tex]
Now this expression could also be written as:
[tex]y^2-25=y^2-5^2[/tex]
This means that the expression is a difference of squares.
Also, we know that:
[tex]a^2-b^2=(a+b)(a-b)[/tex]
Here,
[tex]a=y\ and\ b=5[/tex]
Hence,
[tex]y^2-25=(y+5)(y-5)[/tex]
