X=-3,4,-2/5

Question

Write a polynomical of least dergree for the set of roots 

Answer 1

Jayla,

 

roots, say a and b, are written as factors (x - a) and (x - b) of the polynomial that they are roots for.

∴(x+3)(x-4)(x+2/5) is a polynomial of least degree that has these numbers as roots

I hope this helps
