Answer:
The values of x are x= 2i and x= -2i
Step-by-step explanation:
We need to solve the equation:
2x^2 + 8 =0
Taking 2 common
2(x^2 +4) =0
Dividing both sides by 2
x^2+4 =0
Adding -4 on both sides
x^2 +4 -4 = 0-4
x^2 = -4
Taking square root on both sides we get
√x^2 = √-4
we know √4 = 2 and √-1 = i so answer is:
x = ± 2i
The values of x are x= 2i and x= -2i
The graph is shown in figure attached.
