0 c b a and the roots , of the equation c x^2+b x+a=0 are imaginary, then

Options

  1. A| |+| | 2 =| || |
  2. B1 | | = 1 | |
  3. C1 | | + 1 | | 2
  4. Dnone of these

Correct answer

C. 1 | | + 1 | | 2

Step-by-step solution

Since roots are imaginary. So. discriminant 0 = -b+i 4 a c-b^2 2 c , = -b-i 4 a c-b^2 2 c ,| |=| |= b^2 4 c^2 + 4 a c-b^2 4 c^2 = a c 1
