Question

If alpha and 1/alpha are the zeroes of 4x^2 - x + k + 7. Find the value of k.

Answer 1

Answer:

k = -3

Explanation:

a = 4

b = -1

c = k+7

Product of zeros = c/a

alpha * 1/alpha= (k+7)/4

1 = (k+7)/4

k= 4-7 = -3

Answer 2

Answer:

alpha and one upon alpha are the roots of the polynomial then products of roots will be one and then product is also c/a so c/a = k+7/4
