Question

44. If a and Bare zeroes of x*x-2, then 1/a+1/b
(a) 1/3 (b) 1/4 (c) 1/2 (d) 175

45 If sum of zeroes of qox) kx +2x+3k is equal to their product, then k =

(a) -2/3 (b) -1/3 (c) 2/3 (d) 1/3​

Answer 1

Answer:

For a quadratic polynomial p (x) = kx^2 - 2x - 3k , if sum of zeroes are equal to the product of zeroes, then the value of k is
