Factor the two out...
-2(p^2 + 3p +10)
Now you can see that
(p^2 + 3p +10) becomes (p+5)(p-2)
Thanks LogicalReason that helped alot.
If you're confused on how to solve these (look at LogicalReason's reply before this).
Multiply the term before p^2, in this case 1, with the term with no x, in this case 10.
Then find two factors of 10 that add up to 3. In this case, that's 5 and -2. Those two numbers become the two numbers in the new equation below:
Sorry, I had a typo. The two numbers you multiply are actually 1 and -10, so you need to find the two factors that multiply into -10, that when added together equal three. Logical's reply had (p^2 + 3p +10) when it should have been (p^2 + 3p -10).
The factors are still 5 and -2, though. Just read the above comment, but replace 10 with -10 and it'll make more sense.
