Question

What is the error and how do I explain it

Answer 1

Given :

`(s+5)(s-5)`

The product of the given factors will be as following :

`\begin{gathered} (s+5)(s-5) \\ =s\cdot(s-5)+5\cdot(s-5) \\ =s^2-5s+5s-25 \\ \\ =s^2-25 \end{gathered}`

So, the given is the difference between squares, so, the result will be two terms
