Can anyone help me in explaining subtraction of polynomials please help I’m desperate and I’m pretty much on my own when it come
Sidana [21]

Answer:

Think of combining <u>like terms</u> when subtracting polynomials. For example, 3x² and -2x². They both have x² in common. So, if you were to combine 3x² and -2x², it would be like 3x² + (-2x²). Think of this like 3 + (-2), which equals 1. In this case, it would equal 1x² or x².

Let's take this problem for example: 6x² - 3x + 4 - (-2x² +2x - 2)

Parentheses are super important; The first thing you want to do is distribute the negative sign out to everything inside the parentheses!

So,

6x² - 3x + 4 - (-2x² +2x - 2) *multiply the neg. to -2x², 2x, and -2

Now, if you do that, the equation would now look like:

6x² - 3x + 4 + 2x² - 2x + 2

Now think of combining like terms. Here are the like terms:

6x² <em>- 3x</em> <u>+ 4</u> + 2x² <em>- 2x</em> <u>+ 2</u> (Let's rewrite it to look like this...)

6x² + 2x² <em>- 3x</em> <em>- 2x </em><u>+ 4</u> <u>+ 2</u>

Let's combine the x²'s first, so... 6x² + 2x² = 8x²

Let's combine the x's, so...<em> -3x - 2x = -5x</em>

Let's combine the constants (numbers with no variable), so... <u>4 + 2 = 6</u>

<u />

Your solution should be 8x² - 5x + 6

Construct the exponential function that contains the points (0,2) and (3,54)
erma4kov [3.2K]

The exponential function that passes through (0,2) and (3,54) is a growth function

The exponetial function is y = 2 * 3^x

<h3>How to construct the exponential function?</h3>

The points are given as:

(x,y) = (0,2) and (3,54)

An exponential function is represented as:

y = ab^x

Substitute the points in the equation

2 = ab^0 and 54 = ab^3

Solve 2 = ab^0

a = 2

Substitute 2 for a in 54 = ab^3

54 = 2b^3

Divide by 2

27 = b^3

Take the cube roots of both sides

b = 3

So, we have:

y = ab^x

This becomes

y = 2 * 3^x

Hence, the exponetial function is y = 2 * 3^x

Annette [7]
We can write the sequence out more fully, as we can see each time it is divided by 6.
60, 60/6, 60/6^2, 60/6^3, and so on.
Therefore we know the sequence can be written as u_n= \frac{60}{6^{n-1}}
You can think of this as a graph, i.e. y=60/6^(x-1)
As a result, as x tends to infinity, y tends to 0 (since it effectively becomes 60/infinity). Therefore the sequence converges toward zero.
