With respect to the roots of x2 - x - 2 = 0, we can say that :
Correct Answer: both of them are integers
Explanation:
Given :- x2 - x - 2 = 0
The given equation is of the form
ax2 + bx + c = 0
Here , a = 1 , b = -1 , c = - 2
Now, D2 = b2 - 4ac = ( -1 )2 - 4 x 1 x ( - 2 )
D = √9 = 3
So, roots are rational .
Hence, both the roots must be integers.
