Question

What is the value of the expression when $q=-2,r=-12$ and $s=8$?

$\frac{-q^2-r}{s}$

• A. $-2$
• B. $-1$
• C. $1$
• D. $2$

Answer 1

The correct option is C

$1$

Substitute the values $q=-2,r=-12$ and $s=8$ in the expression $\frac{-q^2-r}{s}$

$$\begin{gathered} \frac{-q^2-r}{s}=\frac{-{(-2)}^2-(-12)}{8} \\ =\frac{-4+12}{8} \\ =\frac{8}{8} \\ =1 \end{gathered}$$

Hence, Option C is correct.
