None of the above
Other:
​

Answer 1

Step-by-step explanation:

checking discriminant,

$d = {b}^{2} - 4ac$

from given equation we can observe

b=5

a=1

c= -2

now calculating d

d= 5² - 4 × 1 × (-2)

d= 25 + 8

d = 33

we can observe that,

d > 0

so we can comment that roots are real and rational
