How do you simplify #[(x^3 - 1)/(x + 4)][(2x - 7)/(x^2 + 3x + 1)]#?
We multiply the numerators with numerators and denominators with denominators.
First, let's look at the numerators.
We multiply the numerators like this:
So if we put them all together, we will get
Now multiply the denominators:
Again, let's put them all together, and we get
We still have to combine the "like terms":
So our final answer is:
