Write a polynomial function $f$ of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros. Write the function in standard form. -5, -1, 2

Answer 1

f(x) = A [x - (-5)] [x - (-1)] (x - 2)

A = 1 (leading coefficient)

f(x) = (x + 5)(x + 1)(x - 2)

Expand to standard form and finish from here.
