give formal proof to show that the following argument forms are valid. P implies, negation of p implies r, r implies s therefore negation of q implies s​

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
