Let $x = - 4 , y = 5$ and $z = - 3$ . Evaluate the expression to find $Q$ $$Q = ( x - y + z ) ^ { 2 }$$
A) $Q = 36$
B) $Q = 4$
C) $Q = - 144$
D) $Q = 144$
E) $Q = 16$

Quizplus · Accepted Answer

Substituting the given values of $x$, $y$, and $z$, we get:
\begin{align*}
Q &= (x-y+z)^2 \
&= (-4-5+(-3))^2 \
&= (-12)^2 \
&= 144 \
\end{align*}
Therefore, the answer is \boxed{\textbf{(D)}}.
