Question

what is the first step to take to solve the radical equation $12 + \sqrt{x^4 - 10} = 8$? (1 point)

\bigcirc add 12 to both sides of the equation.

\bigcirc add 10 to both sides of the equation.

\bigcirc raise both sides of the equation to the second power.

\bigcirc subtract 12 from both sides of the equation.

Explanation:

To isolate the radical term $\sqrt{x^4 - 10}$, we first need to eliminate the constant term 12 that is added to it. This is done by performing the inverse operation of addition, which is subtraction, on both sides of the equation.

Answer:

Subtract 12 from both sides of the equation.
