-10
(a) m= 2
(b) m = 2, -2
9
(c) m = 10,2
(d)
10
m=-2,
9
Question 3
If the roots of the equation x? -8x+a’ -6a =0 are real and distinct, then all possible values
of a will be
(a) 2<a<8
(b) 8<a<-2
(c) -8<a <2
(d) -2<a <8​

Answer 1

Answer:

m= -109 or m=2 so it can be negative that why m=2 is correct one
