1. Answer:

   value of k equals

   [tex] \frac{ \sqrt{5} }{2} [/tex]

   Step-by-step explanation:

   if the roots are equal then the discriminant

   ∆ = b²- 4ac = 0

   [tex] { ( – 8k)}^{2} – 4(5)(4) = 0\\64 {k}^{2} – 80 = 0 \\ 64 {k}^{2} = 80 \\ {k}^{2} = \frac{80}{64} = \frac{5}{4} \\ k = \sqrt{ \frac{5}{4} } = \frac{ \sqrt{5} }{2} [/tex]
