Which of the following is the complete list of roots for the polynomial function (x) = (x2+bx+3) (x+6x+13) ?

if i got you question right then its x = (-13/7) x = (-3 / (2+b))

Step-by-step explanation:

to find the roots you need to make it equal to 0.

(x+6x+13) (2x+bx+3) = 0

(7x+13) ((2+b) x+3) = 0

now there are 2 cases:

-> 7x+13=0 7x = (-13) x = (-13/7) solved

-> (2+b) x+3=0 (2+b) x = (-3) x = (-3 / (2+b)) solved
