Answer 1

Answer:

The correct answer is A. 1 +/- i √31/2

Step-by-step explanation:

Let's use the quadratic formula to solve the equation:

x² - x  + 8 = 0

Let's recall that the quadratic equation is:

x = (-b +/- √(b² - 4ac))/2a

In the equation, a = 1, b = -1, c = 8.

Replacing with the real values, we have:

x = (-b +/- √(b² - 4ac))/2a

x = (- (-1) +/- √(-1² - 4 (-1) (8)))/2(1)

x = (1 +/- √( 1 - 32)/2

x = (1 +/- √( - 31)/2

x = (1 +/- √( -1 * 31)/2

Let's recall that √ -1 = i

x = 1 +/- i √ 31/2

The correct answer is A. 1 +/- i √31/2
