Question

1

Answer 1

can you check the discriminant ?

Answer 2

discriminant (D) = b^2 - 4ac

Answer 3

it is 0

Answer 4

(-b+-sqrt(b^2-4ac))/2a is how we find roots
you just showed that the sqrt part is 0
so you are left with
-b/(2a)

Answer 5

this is only one solution

Answer 6

if D = 0 then it has the same roots

Answer 7

note: if you did not get 0, then the sqrt part would have two answers because we do +-sqrt.

Answer 8

so my answer is d) ?
