We're being asked to solve the given radical equation.
00:03
Well, because both of our radicals are isolated, to get rid of those radicals, we simply need to square both sides of the equation.
00:12
Because when we square a radical, we're undoing it, therefore it gets rid of the radical.
00:17
So we're just left with what's underneath.
00:19
So on the left -hand side, we're just left with n plus 5.
00:22
And the same thing happens on the right -hand side, so we're just left with 5 -n -minus 11.
00:28
And now we just need to solve for n.
00:30
Well, to do this, i'm going to subtract 5n from both sides of the equation.
00:37
Well, n minus 5n is negative 4n, and then plus 5 is equal to negative 11, because those 5s cancel out.
00:45
And now we have a two step.
00:46
So to move to 5, i'm going to subtract 5, which cancels out the fives...
