Question

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros.

Answer 1

where are the given zeros?

Answer 2

yes
-2,-1,1

Answer 3

f(x) = (x + 2)(x + 1)(x - 1)

expand this to get the polynomial

Answer 4

thank you

Answer 5

how do you expand it ?

Answer 6

(x + 1)(x - 1) = x(x - 1) + 1(x - 1) = x^2 - x + x - 1 = x^2 - 1

now work to (x + 2)(x^2 - 1) in the same way

Answer 7

thank you so much
