Answer 1

When you have the zeros of a polynomial (ex. a, b, c) and a leading coefficient (ex. T), writing the polynomial is as easy as this :
P(x) = T(x-a)(x-b)(x-c)
Can you apply this with the zeros you have ?

Answer 2

So it would be as easy as... 4(x-3)(x+2)(x-1/5)?

Answer 3

Yes ! (x+1/5) at the end, but I think it was just a typo.

Answer 4

Yes, a typo- and thank you!

Answer 5

Welcome !
