Which of the following is a polynomial with roots: − square root of 5 , square root of 5 , and −3? a: x^3 − 2x^2 − 3x + 6 b: x^3 + 3x^2 − 5x − 15 c: x^3 − 3x^2 − 5x + 15 d: x^3 + 2x^2 − 3x − 6

Roots: - √5 , √5, and - 3

=> these are factors of the polynomial: (x + √5), (x - √5), and (x + 3).

Multiply those three factors:

(x + √5) (x - √5) ( x + 3) = [x^2 - 5] ( x + 3 ) = x^2 + 3x^2 - 5x - 15

Therefore the polynomial x^2 + 3x^2 - 5x - 15 is a polynomial with the given roots.

option B. x^3 + 3x^2 - 5x - 15
