Question

For what value of ' k ' is -3 a zero of the polynomial x2+ 11 X+ K?

Answer 1

Answer:

Thanks for A2A

Step-by-step explanation:

we want root (or zero) of the above equation to be -3

Therefore,

=> P(x) = 0 (where p(x) is the above equation)

=> x^2+11x+k = 0

=> (-3)^2+11(-3)+k = 0

=> 6-33+k = 0

=> -27+k = 0

=> k = 27

Hence, the value of 'k' should be 27 so that -3 becomes the zero of above equation
