The function f is given in three equivalent forms. Which form most quickly reveals the zeros (or 'roots") of the function? Write one of the zeros.
x= ___​

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.
