Answer:
, or x=1.531 and x=-6.531.
Step-by-step explanation:
The first thing we will do is isolate the radical expression on the left hand side. To do this, we subtract 2 from each side:

To cancel the radical, we square both sides:

Now we will cancel the x on the left hand side by subtraction:
x+14-x = x²-4x+4-x
14 = x²-5x+4
Make the equation equal 0 by subtracting 14 from each side:
14-14 = x²-5x+4-14
0 = x²-5x-10
Now we use the quadratic formula (in our equation, a=1, b=-5 and c=-10):

When you evaluate the square root, you get the answers 1.531 and -6.531.
