Question

for what value of c are the factor of { x2 -cx +
81/16 } the same

Here is
answer for your question:

For equal
roots

b2
- 4ac =0

Here b =
- c and a = 1 , c = 81/16

Therefore,

b2
– 4ac =0

(-c)2
- 4(1)(81/16) = 0

c2
= 81/16

c =
9/4

Therefore
factors are same for c = 9/4

for what value of c are the factor of { x2 -cx + 81/16 } the same ...
