Ответ:
k = -1, -2.
Step-by-step explanation:
4k^2+12k+8 = 0
Divide by 4:
4(k^2 + 3x + 2) = 0
4(k + 1)(k + 2) = 0
k = -1, -2.
Ответ:
k = -1 and k = -2
Step-by-step explanation:
We can use the quadratic formula, which says that for the quadratic
, the solutions are: x = 
or 
.
Here, a = 4, b = 12, and c = 8, so: x =
or 
.
Simplifying, we get k = -1 or k = -2.
Thus, k = -1 and -2.
Hope this helps!
