b)-1
d) {-2, 1}
3.
* 1
c) O
d)-2​

Answer 1

Answer:

-1 is the answer

Step-by-step explanation:

By substituting the value of x=2 in given equation, you can get your answer correct.

Answer 2

Answer:

Step-by-step explanation:

2x²+ kx – 6= 0

one of the zero is 2

2 (2)² + k (2) - 6 = 0

2 (4) + 2k - 6 = 0

8 + 2k - 6 = 0

2 + 2k = 0

2k = -2

k = -2/2

k = -1
