Didn't you mean "Find the possible value or values of z? y is not at all present in this equation.
z^2 - 4z + 4 = 0 can be factored into (z-2)(z-2). Thus, the given equation has two equal, real solutions: z=2 and z=-2.
Answer:
22
Step-by-step explanation:
5+12-2+7
17-2+7
15+7
22
P-23=-3
+23 +23
P=20
so the answer is A
