(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)

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) ...
