Family of Curves
A family of curves is a group of curves that are each described by a parametrization in which one or more variables are parameters. In general, the parameters have more complexity on the assembly of the curve than an ordinary linear transformation. These…
XZ Plane
In order to understand XZ plane, it's helpful to understand two-dimensional and three-dimensional spaces. To plot a point on a plane, two numbers are needed, and these two numbers in the plane can be represented as an ordered pair (a,b) where a and b are…
Euclidean Geometry
Geometry is the branch of mathematics that deals with flat surfaces like lines, angles, points, two-dimensional figures, etc. In Euclidean geometry, one studies the geometrical shapes that rely on different theorems and axioms. This (pure mathematics) ge…
Lines and Angles
In a two-dimensional plane, a line is simply a figure that joins two points. Usually, lines are used for presenting objects that are straight in shape and have minimal depth or width.

#12 from the book

Certainly! Below is the transcribed text formatted as if it were to appear on an educational website. --- ## Exercises on Polynomials and Irreducibility 1. Prove that the polynomial \(x^2 + x + 1\) has no roots in any field of characteristic 3. 2. Show details of the proof that if a monic polynomial with integer coefficients has a root in \(\mathbb{Q}\), then this root must be an integer. 3. If a monic polynomial with integer coefficients has a root in \(\mathbb{Q}\), show that this root must be an integer. 4. Demonstrate how each polynomial is irreducible in \(\mathbb{Q}[x]\), as seen in Example 3. - \(x^4 + 2x^2 + x + 1\) - \(x^4 + x^3 + x^2 + x + 1\) 5. Use Eisenstein's Criterion to show that each polynomial is irreducible in \(\mathbb{Q}[x]\): - \(x^4 - 4x + 22\) - \(5x^4 - 6x^3 + 36x - 6\) 6. Demonstrate that there are infinitely many integers \(k\) such that \(x^4 + 12x^2 - 21x + k\) is irreducible in \(\mathbb{Q}[x]\). 7. Show that each polynomial is irreducible in \(\mathbb{Z}[x]\) by finding a prime \(p\) such that \(f(x)\) is irreducible in \(\mathbb{Z}_p[x]\): - \(x^3 + 6x^2 + x + 6\) - \(7x^7 + x^6 + 9x^4 - 3x + 7\) 8. Provide an example of a polynomial \(f(x) \in \mathbb{Z}[x]\) and a prime \(p\) such that \(f(x)\) is reducible in \(\mathbb{Q}[x]\) but irreducible in \(\mathbb{Z}_p[x]\). 9. Give an example of a polynomial in \(\mathbb{Z}[x]\) that is irreducible in
