Thread: calling all X hunters. Is x undefined?

solve for x

(squareroot of 3 - (squareroot of x + 5)) = 2


**the squaroot of 3 - is also covering the squareroot of x + 5

- 4 = answer?

Is the equation ?

If so, simple substitution shows that x = -4 is not the answer. In fact, there is no answer if x is a real number.

yes that is the correct equation.
I've tried solving for x and got -4 but when i plug back into equation the numbers dont match.
Hence, is this equation undefined?
