Question

37. Find the roots of the equation x - x - 2 = 0 and verify the relation with their coefficients

Answer 1

Answer:

Here, We have :

x^2 -x -2 =0

x^2 + x-2x -2 =0

x (x+1) - 2 (x+1) =0

(x+1) ( x -2) =0

Now , We have:

x+1 =0 , x=-1

or x-2 =0 , x=2.

Therefore, roots are :

x = -1 , 2 Ans.
