Question

Hey can you please help me posted picture of question

Answer 1

The nature of roots of a quadratic equation can be determined from its discriminant.

Discriminant = b² - 4ac

b = coefficient of x term = 2
a = coefficient of squared term = 2
c = constant = 4

So,

Discriminant = 4 - 4(2)(4) = -28

Since the discriminant is negative, the two roots of the given equation will be complex .

Therefore, the answer to this question is option B
