    the factors of x3 + 7x2 - 2x - 14. are (x^2-2) (x+7) ...

    Step-by-step explanation:

    x3 + 7x2 - 2x - 14.

    We will group the terms.

    Make pairs of the terms:

    (x3 + 7x2) - (2x + 14.)

    Now find the common factor of each pair

    x^2 (x+7) - 2 (x+7)

    (x^2-2) (x+7)

    Thus the factors of x3 + 7x2 - 2x - 14. are (x^2-2) (x+7) ...

    (x+7) (x^2-2)

    Step-by-step explanation:

    x^3 + 7x^2 - 2x - 14

    We will factor by grouping

    Take x^2 out of the first two terms and - 2 out of the last 2 terms

    x^2 (x+7) - 2 (x+7)

    Now we can factor out (x+7)

    (x+7) (x^2-2)
