Denae and Gina were trying to solve

“*Let’s start by putting the radicals on opposite sides of the equation and then squaring,*” she said. Her work is shown at right.

“*But there’s still a radical!*” she exclaimed, disappointed.

“*That’s okay,*” said Denae, “*there’s only one now, so we can get the term with the radical by itself and then square everything again.*”

Follow Denae’s advice and solve this equation.
