-4k^2-8k-3 = -3-5k^2
--> -4k^2 -8k -3 +3 +5k^2 = 0k^2 -3k = 0 Apply the quadratic formula Taking a= 1, b= -3 and c= 0. Therell be 2 values for k
\(-4k^2-8k-3 = -3-5k^2 \\ \\ -4k^2 - 8k = -5k^2 \\ \\ 4k^2 + 8k - 5k^2 = 0 \\ \\ -k^2 + 8k = 0 \\ \\ 8k - k^2 = 0 \\ \\ k(8 - k) = 0 \\ \\ k = 0,8 \\ \\\)The final result is: k = 0, 8.
