Answer 1

Answer:

a = -1

b = -1

c = 4

Step-by-step explanation:

The general form of a quadratic expression is:

`ax^2+bx+c`

The given quadratic expression is:

`4-x^2-x`

This may be written as:

`-x^2-x+4`

Comparing this to the general expression, we see that

`\begin{gathered} a=-1 \\ b=-1 \\ c=4 \end{gathered}`
