Question

I don't understand about quadratic equations4-x²-xFind a, b and c

Answer 1

Answer:

a = -1

b = -1

c = 4

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

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