(3n-2)(4n+1) how do i solve this by factoring?

Mathematics

Anni [7]3 years ago

Answer:

12n^2-5n-2

The expression (3n-2)(4n+1) can be factored with the Distributive Property. It cannot be factored with a Least Common Multiple (LCM), for instance, because the terms within each set of parentheses are completely simplified.

Step-by-step explanation:

Part I

.1. (3n-2)(4n+1)\\2. F.O.I.L.: 12n^2+3n-8n-2\\3. Simplify: 12n^2-5n-2\\

Good luck to you!

Answer:

5

Step-by-step explanation:

There are 2 ways to look at this. I will explain both.

First we have the 3-4-5 triangle method, stating that any triangle with sides 3 and 4 will have the last side as 5.

Now, for the more complex way of doing this, we can use the Pythagorean theorem to solve this problem.

Pythagorean theorem: a^2+b^2=c^2

We can use 4 for a and 3 for b

You will now have

4^2+3^2=c^2\\\\16+9=c^2\\25=c^2

Then take √25, or 5.
