Question

Solve the equation for p. Identify any extraneous solutions.
Square root 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 solution.

Answer 1

sqrt(p) = -1 squaring both sides

so what will get ?

Answer 2

sqrt(p) = p^(1/2)

writing the squareroot like exponent

so than now if you squared both sides what will get ?

Answer 3

do you like cooperat anything please ?

Answer 4

(p^(1/2) )^2 = (-1)^2

can you calculi it now ?

Answer 5

I was on phone.
I am mother that doesnt get some things. Dont be so rude if you dont want to answer dont

Answer 6

ok

(p^(1/2))^2 = p^(1/2 *2) = p^(2/2) =p^1 = p

Answer 7

and (-1)^2 = -1 *-1 =
