Question

If one of the zero of the given polynomial is 4,find the value of k (k-2)x2-2x-(k+5)

Answer 1

The value of k is 3..

Answer 2

Step-by-step explanation:

put 4 instead of x and remove brackets wherever u can

k(k-2)x2 - 2x - (k+5) = (k2-2k)16 - 8 - k - 5

=> 16k2 - 32k - k - 13 = 16k2 - 33k -13

simplify this to get 2 zeros

use these zeros and u will get the answer

thank u
