Dear Kristen:
Just multiply the two equations
X + 3
X + 4
____________________
X² -----> First multiply X times X giving X squared
Next Multiply X times 4 giving 4x
X² + 4x Next:
Multiply X times 3 Giving 3x Now also notice the problem is "PLUS"
Now we have :
X² + 4x
+ 3X
_____________________ Now we add giving
X² + 7x so far Next multipoly 3 times 4
Giving X² + 7x + 12 -----> Is what you are looking for.
when you multiply Positive times Negative is always negative.
Hope this helps !
