Question

find the value of k,if x+3 is a factor of 3x²+xk+6​

Answer 1

sorry i had written the answer wrong earlier...

Answer 2

Answer:

Zero of polynomial = x+3 = 0

=x = 0-3

= -3

Now,

3x^2 + xk + 6 = 0

3×(-3)^2 + (-3) × k +6 = 0

3×18 -3k + 6 = 0

54-3k+6. =0

-3k. = 0-54-6

-3k. = -60

k. = -60/-3

k. = 20
