Answer:
d) 4 ± 5i
Step-by-step explanation:
Here we have to use the quadratic formula.
x = 
In the given equation x^2 - 8x + 41 = 0, a =1, b = -8 and c = 41
Now plug in the given values in the above formula, we get
x = 
Simplifying the above, we get
x = 
x = 
[√-100 = √-1 *√100 = i*10 = 10i] because the value of √-1 = i]
x = (8 ± 10i )/2
Now dividing by 2, we get
x = 4 ± 5i
The answer is d) 4 ± 5i
Hope you will understand the concept.
Thank you.

Answer:
for soln 1: X < -2; for soln 2: X < 1
Step-by-step explanation:
This is two set problem involving inequality. Therefore, you have to solve for each side of the inequality to know the values of X for each sides.
1 < X + 3 < 4
Soln 1. solve for the first side of the inequality
1 < X + 3
1 - 3 < X
-2 < X
X > -2
soln 2: solve for the second side of the inequality
X +3 < 4
X < 4 - 3
X < 1
Therefore, X > -2; X < 1
