Question

If alpha and beta are the two zeros of the polynomial 21x²-x-2. Find the quadratic polynomial whose zeros are 2 alpha and 2 beta.

Answer 1

Step-by-step explanation:

alpha = 1/3 and beta = -3/7

so, the quadratic polynomial will be

x^2 - (sum of zeroes)x + product of zeroes

x^2 - 16/21x + 1/7
