We have seen that the b 2 - 4 ac portion of the quadratic formula, called the discriminant , can tell us the type of roots of a quadratic equation. The quadratic formula can also give us information about the relationship between the roots and the coefficient of the second term and the constant of the equation itself. Consider the following:. We can also see these relationships emerge from factoring the quadratic equation. The roots will be represented as r 1 and r 2.

The quotient rule is a formula for finding the derivative of a fraction. Whenever you require assistance on basic concepts of mathematics or even polynomial functions, Rational-equations.

I was able to understand the cubic equation's part but I am completely lost with the general part i.

In mathematics , a univariate polynomial of degree n with real or complex coefficients has n complex roots , if counted with their multiplicities. They form a set of n points in the complex plane. This article concerns the geometry of these points, that is the information about their localization in the complex plane that can be deduced from the degree and the coefficients of the polynomial. Some of these geometrical properties are related to a single polynomial, such as upper bounds on the absolute values of the roots, which define a disk containing all roots, or lower bounds on the distance between two roots. Such bounds are widely used for root-finding algorithms for polynomials, either for tuning them, or for computing their computational complexity.

## Basics of Polynomial Theory

In algebra , a quartic function is a function of the form. A quartic equation , or equation of the fourth degree, is an equation that equates a quartic polynomial to zero, of the form. Sometimes the term biquadratic is used instead of quartic , but, usually, biquadratic function refers to a quadratic function of a square or, equivalently, to the function defined by a quartic polynomial without terms of odd degree , having the form.

*Summary: In algebra you spend lots of time solving polynomial equations or factoring polynomials which is the same thing.*

### Geometrical properties of polynomial roots

To find the conditions when roots are connected by given relations. Sometimes the relation between roots of a quadratic equation is given and we are asked to find the condition i.

The Factor Theorem says that if a polynomial p(x) has root r, then x−r divides p(x). Since polynomial with complex coefficients always have exactly the same.

Стратмор закрыл лицо руками. - Хорошо. Это на нижнем этаже. Возле фреоновых помп. Сьюзан повернулась и направилась к двери, но на полпути оглянулась.

Он молился не об избавлении от смерти - в чудеса он не верил; он молился о том, чтобы женщина, от которой был так далеко, нашла в себе силы, чтобы ни на мгновение не усомнилась в его любви. Он закрыл глаза, и воспоминания хлынули бурным потоком. Он вспомнил факультетские заседания, лекции - все то, что заполняло девяносто процентов его жизни. Вспомнил о Сьюзан. Это были простые воспоминания: как он учил ее есть палочками, как они отправились на яхте к Кейп-Коду.

В таком случае ему не нужно будет передавать пароль кому-то. Возможно, он работал в одиночку. Стратмор хмыкнул.
