2n³ - 3n² - 7n + 3

Step-by-step explanation:

Hi there! Don't worry, polynomials seem hard but you will get them with practice.

I am going to show you 2 methods of multiplying polynomials. These methods are universal, or they work with any polynomial multiplication problem:

Method 1: Distributive Property

This is perhaps the most common method. You distribute 1 value to another or multiply each and every single term.

Let's solve!

(n² - 3n + 1)(2n + 3)n²(2n + 3) - 3n(2n + 3) + 1(2n + 3) n²(2n) + n²(3) - 3n(2n) - 3n(3) + 2n + 3 See how I distributed the values?2n³ + 3n² - 6n² - 9n + 2n + 3

Now, we add up like terms. Like terms should have the same coefficient and should be raised to the same power.

2n³ + 3n³ - 6n² - 9n + 2n + 3 2n³ - 3n² - 7n + 3

There you have it! This is how you solve with The distributive Property Method.

Method 2: Area Model

This is the next universal method, Area modeling.

Area models can be set up by the number of terms we have. In the first polynomial we have three terms:

n²-3n+1

Just for this method, keeping the positive signs helps.

For the binomial, we have two terms (hence, binomial)

2n+3

We set up our are model like this, with the terms laid out as side lengths of a rectangle. (Attachment "A")

Next, we find the area of each individual tile. (Attachment "B")

Now, we add like terms. Something nice about area models is that most of the time, the like terms are matched up in a diagonal. (Attachment "C")

Answer from: Quest

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

⇒ option b is correct.

Prove (a) cosh2(x) − sinh2(x) = 1 and (b) 1 − tanh 2(x) = sech 2(x). solution (a) cosh2(x) − sinh2(x) = ex + e−x 2 2 − 2 = e2x + 2 + e−2x 4 − = 4 = . (b) we start with the identity proved in part (a): cosh2(x) − sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 − sinh2(x) cosh2(x) = 1 or 1 − tanh 2(x) = .
