Answer:
Thus, the two root of the given quadratic equation   is 2 and -3 .
  is 2 and -3 .
Step-by-step explanation:
Consider, the given Quadratic equation, 
This can be written as ,  
We have to solve using quadratic formula,
For a given quadratic equation  we can find roots using,
 we can find roots using,
 ...........(1)
  ...........(1)
Where,   is the discriminant.
 is the discriminant.
Here, a = 1 , b = 1 , c = -6
Substitute in (1) , we get,




 and
 and 
 and
 and 
 and
 and 
Thus, the two root of the given quadratic equation  is 2 and -3 .
 is 2 and -3 .
