Find the value of 'k' if the expression $(4 - k) x^{2} + 2 (k + 2) x + 5 k + 1$ is a perfect square

k

a_{k} = cos (\frac{k π}{7}) + i sin (\frac{k π}{7})

\frac{12 \sum k = 1 | a_{k + 1} - a_{k} |}{3 \sum k = 1 | a_{4 k - 1} - a_{4 k - 2} |}

k

a_{k} = cos (\frac{k π}{7}) + i sin (\frac{k π}{7})

\frac{12 \sum k = 1 | a_{k + 1} - a_{k} |}{3 \sum k = 1 | a_{4 k - 1} - a_{4 k - 2} |}

{log}_{k} x . {log}_{5} k = {log}_{x} 5, k \neq 1, k > 0
