Question

Reena says teena that her age (in years) is equal to the sum of the square of the zeros of the polynomial
$x {}^{2} + 6x + 10$
Further, she asserts that after 2 years her age (in years) will be equal to the sum of the product of the zeros taken two at a time of the polynomial
$x {}^{3} - 7x {}^{2} + 20x - 12$
(a) find the age of Reena as per her first statement.

(b) what will be the age of Reena after 2 years for her second statement.

(c) comment on the behaviour of Reena. ​

sum of zeros =-b/a =-6/10

age can't be in negative so question is wrong

if you admit the same then like
