Hi !
p(x) = 2x² + x + k
given ,
p(3) = 0
x = 3
p(3) = 2 × 3² + 3 + k
18 + 3 + k = 0
21 + k = 0
k = -21
value of k is -21
p(x) = 2x² + x + k
given ,
p(3) = 0
x = 3
p(3) = 2 × 3² + 3 + k
18 + 3 + k = 0
21 + k = 0
k = -21
value of k is -21

Hi
3 is a zeroes of a polynomial
p (x) = 2x² + x - k
p(3) = 2 × 3² + 3 + k
18 + 3 + k = 0
21 + k = 0
k = -21
