Question

for what value of k is -3 a zero of the polynomial X square + 11 x + k

Answer 1

ANSWER :
_______________

x² + 11x + k = 0.

Since, Zero is given, = - 3.

Putting x = - 3,in the given equation.

( - 3 )² + 11 ( - 3 ) + k = 0.

9 - 33 + k = 0.

-24 + k = 0.

K = 24.

Answer 2

(-3)sq+11×(-3)+k=0

=>9+(-33)+k=0

=>k+(-24)=0

=>k=24
