Answer:
The roots are not real.
Step-by-step explanation:
To prove : The roots of I/2 +9 (1-k) are real for all real values of k ?Solution :
The roots are real when discriminant is greater than equal to zero.
i.e b2-4ac>0 But the roots are imaginary therefore the roots of the given equation are not real for any value of k.If x²+kx+k=0, find the value of k, If the roots are real & equal.
