Option (c) is correct.

The complete factored form of her polynomial is (3x^2+8)(x-5)

Step-by-step explanation:

Given : Pascha is factoring the polynomial, which has four terms.

3x^3-15x^2+ 8x- 40 is factored as 3x^2(x-5)+8(x-5)

We are required to choose the completely factored form of her polynomial from the given options.

Factored form of a polynomial is writing the polynomial in the smallest form so that when we multiply we get the same original polynomial.

Consider 3x^2(x-5)+8(x-5)

Taking (x-5) common from both terms , we get,

$3x^2(x-5)+8(x-5) \Rightarrow (3x^2+8)(x-5)$

Thus, we obtained (3x^2+8)(x-5)

Hence, option (c) is correct.

The complete factored form of her polynomial is (3x^2+8)(x-5)
