Question

Plz help me out!!!!!!!!!

Answer 1

Answer:

Step-by-step explanation:

The discriminate part of the quadratic solution is sqrt(b^2 - 4ac). If this is  less than 0, then you get an imaginary result.

a = 2      b= 4     c = 2

sqrt(4^2 - 4 * 2 * 2)

sqrt(16 - 16) = 0

a does not give any imaginary roots.

Try D

a = 3        b= 2       c = 1

sqrt(2^2 - 4*3 * 1)

sqrt(4- 12)

sqrt(-8)

This gives you an imaginary zero because - 8 has an imaginary sqrt.
