Question

If 2 is a zero of polynomial4 2 − 6 + ,find the value of k

Answer 1

Answer:

k = 4

Step-by-step explanation:

Given f(x)=4y^2 - 6y - k

Given that 2 is the zero of the polynomial .

f(2) = 0

= 4(2)^2 - 6 (2) - k = 0

= 16 -12 - k = 0

= 4 - k = 0

= k = 4

Therefore the value of k is 4
