We'll use the formula D+=+b%5E2+-+4ac. In this case, a+=+k, b+=+-6, c+=+1 and the discriminant is D+=+0

Plug the values into the formula and solve for k.

D+=+b%5E2+-+4ac

0+=+%28-6%29%5E2+-+4%28k%29%281%29

0+=+36+-+4k

4k+=+36

k+=+36%2F4

k+=+9

Let me know if you need more help or if you need me to explain a step in more detail.
