Question

4 k square + 8 - 4 is equal to zero​

Answer 1

Answer:

question is this I think..

4k²+8-4= 0 ??

answer:-

4k² +8-4=0

4k² +4=0

4k² = 0-4

4k²= -4

k² = -4-4

k² = -8

I hope this answer is ryt..I tried my best...

Answer 2

Answer:

k = -1 ± √2   or   k = ±√-1

Step-by-step explanation:

I Didn't Think the Question is correctly Written so I make 2 Cases

Case 1 ; 4k²+8k-4= 0

k² + 2k - 1 = 0

k = [-2 ± √4+4]/2

k = -1 ± √2

Case 2 ; 4k²+8-4= 0

4k²+ 4 = 0

k² + 1 = 0

k = ±√-1
