Factor:
1)
To make things a little easier, you can temporarily substitute another variable, say x,for (p+3), to give you:
Factoring this trinomial, you'll get:
Now you can re-substitute the (p+3) for x, to get:
Now you simplify this expression.
...and there you have it!
---------------------------------------------
Check:
Let's first multiply the factors using FOIL:
=
Now we'll expand the given trinomial that you were asked to factor:
=
2) Factor:
First factor
Now, to simplify the calculations a bit, temporarily substitute x for , but only inside the parentheses!
Now factor the trinomial in x.
Finally, you can replace the x with
...so you were close!
------------------------------
Check:
= ...which is exactly what you started with!
