Question

Decide whether or not the equations are equivalent.
-$$\begin{array} { l } 
x = - 3 \
x ^ { 2 } = 9
\end{array}$$
A) Not equivalent
B) Equivalent

Quizplus · Accepted Answer

The first equation, $x = -3$, specifies a single value for $x$, while the second equation, $x^2 = 9$, has two solutions: $x = 3$ and $x = -3$. Since the second equation includes an additional solution not present in the first, the equations are not equivalent.
