Answer
$\left\{-\sqrt{10}, \sqrt{10}\right\}$
Work Step by Step
Subtract 1 on both sides of the equation to obtain:
$5x^2 = 50$
Divide 5 on both sides of the equation to obtain:
$x^2=10$
Take the square root of both sides to obtain:
$x = \pm \sqrt{10}$
Thus, the solution set of the given equation is $\left\{-\sqrt{10}, \sqrt{10}\right\}$.
