Question

Heeeeeereee. . . . .



please solve this with explaination So that i can understand. . . . . . ​

Answer 1

Answer:

k = 9

Step-by-step explanation:

Sum of the zeros = $\frac{ - a}{b} = \frac{ k}{3}$

Given that,

Sum of the zeros = 3

$\frac{k}{3} = 3$

$k = 9$

Answer 2

Answer:

9

Step-by-step explanation:

zeros of the polynomial are alpha and beta

alpha + beta =3

by comparing roots with questions we can get the formula alpha + beta =-b÷a (a=3,b=-k,c=6)

-b÷a=3

-(-k)÷3=3

k÷3=3

k=9
