Question

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!

Answer 1

if u answer my question i will answer yours

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
