Answer:

0

Step-by-step explanation:

Read off the coefficients of this quadratic polynomial x^2 - 3x + 8 = 0:

a = 1, b = -3, c = 8.

Now calculate the discriminant, b² - 4ac:

(-3)² - 4(1)(8) = 9 - 32 = -23

Because the discriminant is negative, the two roots will be complex.  There are no real roots.  Correct answer is B (0).
