The roots of 2x2–6x+8=0 are __________

Question - The roots of

2 x^{2} - 6 x + 8 = 0

are ___________.

Options:

A . real, unequal and rational

B . real, unequal and irrational

C . real and equal

D . imaginary

Answer: Option D
:
D
Step 1:For

2 x^{2} - 6 x + 8 = 0

, value of discriminant

D = (- 6)^{2} - 4 (2) (8) = 36 - 64 = - 28

Step 2:Since

D < 0

, roots are imaginary.
