This week in precalc 11, I learned how to multiply fractions with variables. Let’s get started
So there are 4 easy steps, first factor if possible, multiply the numerator, multiply the denominator, then simplify across.
Here is an example.
First we should see if there is anything that is factorable and it looks like there isn’t anything. Then we just multiply across (Just Do It).
Let’s look at our next example. We can see that 2x+4 can be factored so let’s do that. After we factor out the 2, we see that we end up with 2(x+2) and we also see that there is the same expression across the equation, so we can just cancel those out.
Since we have 2 of the same expressions across from each other and is not tied to any addition or subtraction, we can just cancel them out. So we end up with this.
