Suppose u={ 1, 2, 3, 4, 5, 6, 7, 8} is the universal set and p= { 2, 4, 6, 8} what is p'

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

it is x=-4

step-by-step explanation:

answer is c
