Question

:) The value of K for which 3 is a zeros of the polynomial 2x² + K is​

Answer 1

Answer:

If 3 is a zero then

put 3 in place of x

2(3)^2 + K = 0

2*9 + K = 0

18 + K = 0

K = -18

Therefore value of K is -18

and yeah plz dont get confused between

value of k and x

just forget about k and always put the given value of zero in place of x
