Which of the following is a polynomial with roots: − square root of 5 , square root of 5 , and −3?
tresset_1 [31]
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.

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

Pavel [41]

Answer:

The fourth option is the correct answer

Step-by-step explanation:

The given expression is

-2n(5+n-8-3n)

Given that n=3,We substitute the value of n into the expression and simplify.

This implies that,

-2n(5+n-8-3n)=-2(3)[5+3-8-3(3)]

=-6(5+3-8-9)

=-6(-9)

=54

Hence the answer is 54
