Question

solve $x^{2}=45$, 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.\ $x = \square$

Explanation:

Step1: Take square root of both sides

$x = \pm\sqrt{45}$

Step2: Simplify the radical

$\sqrt{45} = \sqrt{9\times5} = \sqrt{9}\times\sqrt{5} = 3\sqrt{5}$

Answer:

$3\sqrt{5}, -3\sqrt{5}$
