Suppose that 2x^2 - 5x + k = 0 is a quadratic equation with one solution for x. Express k as a common fraction.
Thanks for helping in advance!

if u answer my question i will answer yours

Step-by-step explanation:

2x^2  - 5x  +  k  =   0

If  this has one solution then the discriminant  = 0

So

(-5)^2  - 4 (2) k   = 0

25  - 8k  = 0

25  =  8k

25/8  = k

assuming you mean addition: addition and subtraction are reverse operations.
