Question

8k2 + 4k - 3k2 + 3^2 - k + 5 Please let me

Answer 1

8k^2 + 4k - 3k^2 - k +3^2 + 5,
Combine like-terms:
5k^2 + 3k + 14,
Use Quadratic Formula:
K = (-3 +- sqrt(3^2 - 280)) / 10,
K = (-3 +- sqrt(-271)) / 10,
K = (-3 +- sqrt(271*-1)) / 10
K = (-3 +- 16.5i) / 10,

K = -0.3 + 1.65i and -0.3 - 1.65i.
