Solve 2x^2 + 26 = 0 to identify the roots

2nd and 3rd part of the problem:

The roots are imaginary because of the NEGATIVE RADICAND

There are two roots because of the NEED TO IDENTIFY + AND- ROOTS OF THE RADICAND

Step-by-step explanation:

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
