Question

Find the discriminant and the number of real roots for this equation. x2 + 2x+8 = 0

Answer 1

Answer:

Option 'D' is correct.

Step-by-step explanation:

Since we have given that

We will first find the "Discrimination":

Since discriminant is less than 0 i.e. D<0.

So, there will no real roots.

Hence, D = -28 and there is no real roots.

Therefore, Option 'D' is correct.
