This is a way I was told to do it, hopefully it help you. But what you want to do is try and get rid of the number farthest away from x, which would be 3, then you want to get rid of the five because it’s the closest to the x. Think of it as someone who doesn’t like people and they are trying to get rid of them.

I’m not great at explaining things but I hope this helps you!!!

Let V be the vector space P3[x] of polynomials in x with degree less than 3 and W be the subspace
Pepsi [2]

By definition, the span of two vectors is the set of all possible linear combinations of said vectors. So, any element in W is obtaining by choosing two numbers a,b and building

a(7-8x-8x^2)+b(x^2-(5+6x)) = -8ax^2-8ax+7a+bx^2-6bx-5b

(a)

So, you can show a nonzero polynomial in W by choosing any values of a and b, as long as they're not both zero. To keep it as simple as possible, we can choose for example a=1, b=0 and we obtain one of the base vectors of W:

7-8x-8x^2

(b)

Factoring the powers of x, we see that a generic polynomial in W looks like

(b-8a)x^2-(8a+6b)x+7a-5b

So, we must build a polynomial

dx^2+ex+f

such that it is not possible that

\begin{cases}d=b-8a\\e=8a+6b\\f=7a-5b\end{cases}

For example, let's try the polynomial x^2+x+1

We should solve the system

\begin{cases}b-8a=1\\8a+6b=1\\7a-5b=1\end{cases}

And you can check that it has no solutions. So, the polynomial x^2+x+1 does not belong to W. On the other hand, it surely belongs to V, because it is a polynomial with degree less than 3. So, the polynomial x^2+x+1 belongs to V/W.

−−→AB=(xy)<br><br> What values should <br> x<br> and <br> y<br> take?
laiz [17]

The values of x and y are 2 and 0, respectively

The complete question is given below:-

−−→AB=(xy) a line is given in the question from the image given in the question What values should x and y take?

<h3>How do determine the value of x?</h3>

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

From the graph, we have the following highlights:

Point A is at:

A = 2

The point B is located at:

B = 0

The coordinate (x,y) is represented as:

(x,y) = (A,B)

So, we have:

(x,y) = (2,0)

Hence, the values of x and y are 2 and 0, respectively
