Question

if the sum of the zeros of the polynomial f(x)=(k square -14)x square -2x-12 is 1 which is one of the possile values of k
​

Answer 1

Answer:

4

Step-by-step explanation:

Let alpha & beta be the zeroes of the given polynomial........

Sum of zeroes = 1

alpha + beta = 1

-(-2)/(k^2 - 14) = 1 [ alpha + beta = -b/a ]

k^2 - 14 = 2

k^2 = 2 + 14 = 16

k = sq.root(16) = 4
