Question

Which of the following equations has no real
roots?
(A). 2x² – 3x + 5 = 0 (B)
(B) 3x² – 2x -8=0
(C) 4x² + 4x + 1 = 0 (D) 3x² - 4x + 1 = 0​

Answer 1

Answer:

(A)is not real equation

Answer 2

Answer:

A

Step-by-step explanation:

Discriminant,D=b^2-4ac

If D=0, it has only 1 real zero.

If D>0 (+ve) , it has 2 real zeroes.

If D<0 (-ve) , it has no real zeroes.
