write a polynomial function f of least degree that has rational coefficients of 1, and given zeros. Write a function in standard form. -2, 1, +√7

Question

√

Answer 1

x^4 + x^3 -9x^2 -7x + 14

(x+2)(x-1)(x^2-7) expand and get a 4th degree polynomial with rational coefficients

and leading coefficients of 1 for the x^4 and x^3 terms
