Question

Find k if the sum of roots of equation x2-x+k(2x-1)

Answer 1

The ques. Is incomplete ...But I guess you equal and real,

Than Discriminant = 0

That is, b^2 - 4ac = 0

b =(2k-1)

c =- k

a = 1

b2-4ac = 1 +4k^2 -4k - (4×-k×1)=0

= 1 + 4 k^2 -4k + 4k=0

=1= -4k^2

So, the answer (if u will calculate) is actually wierd..Plz recheck the ques. And the method will be the same anyways

Try it yourself just by putting discriminant
