Question

solve the equation by graphing the related function.
$x^2 + 3 = 0$
what is(are) the solution(s)? select the correct choice and fill in any answer boxes in your choice below.
a. $x = \square$
(simplify your answer. use a comma to separate answers as needed.)
b. the answer is not a real number.

Explanation:

Step1: Rearrange the equation

$x^2 = -3$

Step2: Analyze real number constraints

For all real numbers $x$, $x^2 \geq 0$.

Step3: Compare with equation result

$-3 < 0$, so no real $x$ satisfies $x^2=-3$.

Answer:

B. The answer is not a real number.
