The question can be interpreted as follow:


(4x^2+x-5)-(5x^2-1)

Step 1: Open parentheses


\begin{gathered} 4x^2+x-5-5x^2-(-1) \\ 4x^2+x-5-5x^2+1 \end{gathered}

Step 2: Group the terms by grouping similar terms


4x^2-5x^2+x-5+1

Step 3: simplify the expression


-x^2+x-4

Therefore the answer is

-x^2 + x - 4

The correct answer is option C
