Answer:
x²-7x+12
Step-by-step explanation:
When doing these types of problems, you have to multiply each term with each other.
Lets take a look at this.
We have to multiply each term with each other, so x times x =x²
x times -3=-3x
x times -4=-4x
-3 times -4=12
now we add them all up to get
x^2 -7x + 12
(x-3) (x-4)
Expand
x^2 -3x - 4x + 12
Simplify
Hope that helps!
