# Which polynomial is a difference of two squares? x^{2} + 25 - 10x and x^{2} + 25 + 10x

We will use the concept of polynomial in order to find the difference.

## Answer: The polynomial that is the difference between two squares is 20x.

Let us see how we will use the concept of polynomial in order to find the difference.

**Explanation**:

Let us consider p_{1} = x^{2} + 25 + 10x and p_{2} = x^{2} + 25 - 10x

Now we have to calculate p_{1} - p_{2}.

p_{3} = p_{1} - p_{2}

= (x^{2} + 25 + 10x) - (x^{2} + 25 - 10x)

= 20x
