Question

The roots of a polynomial are (-5/3) and (2/7). What are possible factors for a polynomial?

Answer 1

what polynomials?
I see 2 fractions there

Answer 2

if the roots are a and b, then the polynomial would be (x-a) (x-b)

so for your case they are -5/3 and 2/7

so it would be (x+5/3) (x- 2/7) = 1/21 (3x+5) (7x-2)

Answer 3

heheh, the original posting was edited
now it says the "roots" :P

Answer 4

anyhow, as @moneybird said :)

Answer 5

How do you know to do that?
