Question

If 2 is a zero of the polynomial f(x) = x2 – 8x + k, then find the value of k.

Answer 1

Answer:

k=12

Step-by-step explanation:

$f(x)=x^{2} -8x+k\\f(2)=4-16+k\\ \\ =-12+k\\k-12=0\\k=12$

Answer 2

Answer:

THE VALUE OF K IS 12

Step-by-step explanation:

Given,

2 is the zero of the polynomial

So,. x=2

f(x)=f(2)=0

f(2)=2(2)-8(2)+k=0

=4-16+k=0

=-12+k=0

=k=0+12

=k=12
