1. Identify the coefficients:
a = 4, \hspace{5pt} b = -6, \hspace{5pt} c = -5
2. Use the quadratic formula:
k=\frac{-b \pm\sqrt{b^2 - 4ac}}{2a}
3. Calculate discriminant:
b^2 - 4ac = (-6)^2 - 4 \cdot 4 \cdot (-5) = 36 + 80 = 116
4. Simplify:
k=\frac{6 \pm\sqrt{116}}{8}=\frac{6 \pm2\sqrt{29}}{8}
5. Final answer:
k=\frac{3 \pm\sqrt{29}}{4}
