Question

If the sum of the zeroes of the quadratic polynomial x2 + 2x + 3k is

equal to the product of its zeroes, then k =?​

Answer 1

Answer:

k = -2/3

Step-by-step explanation:

let ax^2 +bx + c be quadratic equation

Sum of roots(zeroes) = -b/a = -2/1 = -2

prodcts of roots(zeroes) = c/a = 3k/1 = 3k

A/c to question,

sum of zeroes = product of zeroes

=> -2 = 3k

=> k = -2/3
