Question

Find a polynomial function with integral coeffecients that has the given numbers as roots: 2, 1, -2

Answer 1

u have the roots x=2 or x=1 or x=-2 then the following are the factors of the polynomial:
\[ \large x-2\qquad x-1\qquad x+2 \]
the polynomial is therefore
\[ \large f(x)=(x-2)(x-1)(x+2)=.. \]
