Question

Determine whether n^2-10n-25 is a perfect square trinomial. If so, choose the correct factoring. A. NoB. Yes;(n+5)^2C. Yes;(n+5)(n-5)D. Yes;(n-5)^2

Answer 1

The given polynomial is,

`\begin{gathered} n^2-10n-25=n^2-2*5* n+5^2-5^2-25 \\ =(n-5)^2-50 \end{gathered}`

Thus, the given polynomial is no a perfect square.

Thus, Option (a) is correct.
