Question

please answer this it is urgent ​

Answer 1

Answer:

k=15/12

Step-by-step explanation:

x=(-4)

(k-1)x²+kx+1=0

(k-1)(-4)²+k(-4)+1=0

(k-1)16+k(-4)+1=0

16k-16-4k+1=0

16k-4k-16+1=0

12k-15=0

12k=15

k=15/12

Therefor, the value of k is 15/12.

Answer 2

Answer:

p(x) = 0

If x = -4 then p(-4) = 0

Now

(k-1)x^2 + kx + 1 = 0

(k-1)(-4)^2 + (-4k) + 1 =0

16k-16 -4k + 1 = 0

12k -15 = 0

12k = 15

k = 15/12
