Factor completely:
x^3+x^2-25x-25
= x^2(x+1)-25(x+1)
= (x+1)(x^2-25)
= (x+1)(x-5)(x+5)

Factor completely:
First, factor by grouping, as follows:
Notice the sign change in the last term because of the added parentheses. Now fctor from the first group and 25 from the second group.
Factor out the (x+1)
Now notice that the second factor is the difference of squares: and you can factor this.
...and this is as far as you can go!
