Sketch the points (0,5,2),(4,0,-1),(2,4,6) and(1,-1,2) o a single set of coordinate axes?
nordsb [41]
Explanation:
As points have three coordinates i.e. x, y and z hence the sketch of the given four points is drawn in 3D shape and for that picture is attached here with this answer.
Points are given in the format as below
(value of x-coordinate , value of y-coordinate , value of z-coordinate)
In the attachment:
Point A = (0,5,2) (in blue color)
Point B = (4,0,-1) (in purple color)
Point C = (2,4,6) (in orange color)
Point D = (1,-1,2) (in black color)
When x is zero there will never be an interception of the line as x=0 is an asymtope
If the roots to such a polynomial are 2 and
![1+\sqrt2](https://tex.z-dn.net/?f=1%2B%5Csqrt2)
, then we can write it as
![(x-2)(x-(1+\sqrt2))](https://tex.z-dn.net/?f=%28x-2%29%28x-%281%2B%5Csqrt2%29%29)
courtesy of the fundamental theorem of algebra. Now expanding yields
![(x-2)(x-1-\sqrt2)=x^2-2x-(1+\sqrt2)x+2(1+\sqrt2)=x^2-(3+\sqrt2)x+2+2\sqrt2](https://tex.z-dn.net/?f=%28x-2%29%28x-1-%5Csqrt2%29%3Dx%5E2-2x-%281%2B%5Csqrt2%29x%2B2%281%2B%5Csqrt2%29%3Dx%5E2-%283%2B%5Csqrt2%29x%2B2%2B2%5Csqrt2)
which would be the correct answer, but clearly this option is not listed. Which is silly, because none of the offered solutions are *the* polynomial of lowest degree and leading coefficient 1.
So this makes me think you're expected to increase the multiplicity of one of the given roots, or you're expected to pull another root out of thin air. Judging by the choices, I think it's the latter, and that you're somehow supposed to know to use
![1-\sqrt2](https://tex.z-dn.net/?f=1-%5Csqrt2)
as a root. In this case, that would make our polynomial
![(x-2)(x-(1+\sqrt2))(x-(1-\sqrt2))=x^3-4x^2+3x+2](https://tex.z-dn.net/?f=%28x-2%29%28x-%281%2B%5Csqrt2%29%29%28x-%281-%5Csqrt2%29%29%3Dx%5E3-4x%5E2%2B3x%2B2)
so that the answer is (probably) the third choice.
Whoever originally wrote this question should reevaluate their word choice...
Answer: I think the answer is 16384!
