1) Solve the equation for p. Identify any extraneous solutions. √p=-1
A) -1 is a solution of the original equation. 1 is an extraneous solution.
B) 1 is a solution of the original equation.
C) 1 is a solution of the original equation. -1 is an extraneous solution.
D) There is no real solution.


If this helps, the p is only covered by the square root sign, and the = sign and -1 is not covered. Thank you so much for any help, since I am confused about this problem.

  2. Good answer. By definition, √p is positive.

    In fact 1 is an extraneous solution.
