Question

what is the sum of the coefficients of the following polynomial?12x^3+9x^2+3x​

Answer 1

$\alpha + \beta \\ \alpha \beta$

a+b=-b/a

ab=c/a

1st

Let alpha beta be zeroes of the polynomial then

The sum of the zeroes

=a+b =-b/a

-9/3=-3

So the sum is - 3 and

Product (not mention but i am answering)

ab=c/a

3/12=1/4 so thank u so much

Answer 2

Answer:

the sum of the coefficient are 12+9+3=24.
