Start with the given expression
Subtract 3 from both sides
Since this equation is never true, there are no solutions (you cannot take a square root and get a negative number). But for the sake of the problem lets see what happens...

Square both sides. Both sides will be positive so we will have 1 answer

Subtract 1 from both sides
Divide both sides by 4


Check:

Plug in x=2



This is not true. We should have . But since we cannot take a square root and get a negative number, we have no solution.
