Question

For what value of k is -2 a zero of polynomial3x^2+4x+2k

Answer 1

Answer:

2

Step-by-step explanation:

3x² + 4x + 2k = 0            

subsitituing -2 in the equation we get

3[-2]² + 4[-2] +2k = 0

12 + {-8} +2k = 0

4 + 2k = 0

2k = 4

k = 4/2 = 2

therefore when the value of k is 2 and the zero is -2 the answer will be 0...
