Question

solve $x^{2}=15$, where $x$ is a real number. simplify your answer as much as possible. if there is more than one solution, separate them with commas. if there is no solution, click
o solution.\

Explanation:

Step1: Take square root of both sides

$x = \pm\sqrt{15}$

Step2: Verify real solutions

$\sqrt{15}$ and $-\sqrt{15}$ are real numbers, so both are valid.

Answer:

$\sqrt{15}, -\sqrt{15}$
