Question

Write a polynomial of least degree with roots 3 and -7.

Write your answer using the variable x and in standard form with a leading coefficient of 1.

Answer 1

The polynomial of least degree with roots 3 and -7 is given by:

(x - 3)(x + 7) = x^2 + 4x - 21

the polynomial in standard form with a leading coefficient of 1 is:

f(x) = x^2 + 4x - 21
