SOLUTION: 2k^2+16k=-12 what i have already k^2+8k=-6 (k^2+8k+16)=-6+16 square root of (x+4)^2 square roof of (10) what is the vertex? solve by compleating the square

Question 677395: 2k^2+16k=-12
what i have already
k^2+8k=-6
(k^2+8k+16)=-6+16
square root of (x+4)^2 square roof of (10) what is the vertex? solve by compleating the square

y =
...
y - 12 =
...
y - 12 = 2()
...
y - 12 + 2(16) = 2()
...
y - 12 + 32 = 2
...
y + 20 = 2
...
y = 2 + -20
...
Using y=a + k
where vertex is (h,k)
...
Vertex is: (-4,-20)
