#### Complex equation

## What is a complex solution?

In Algebra 1, you found that certain quadratic equations had negative square roots in their solutions. When this occurs, the equation has no roots (or zeros) in the set of real numbers. The roots belong to the set of complex numbers, and will be called “complex roots” (or “imaginary roots”).

## What are complex factors?

The factors that are first-degree polynomials are real roots of the original polynomial. Therefore, whenever a complex number is a root of a polynomial with real coefficients, its complex conjugate is also a root of that polynomial. As an example, we’ll find the roots of the polynomial x^{5} – x^{4} + x^{3} – x^{2} – 12x + 12.

## How do you solve complex roots?

In relation to quadratic equations, imaginary numbers (and complex numbers) occur when the value under the radical portion of the quadratic formula is negative. When this occurs, the equation has no roots (zeros) in the set of real numbers.

## Is 6 a complex number?

A complex number is a number of the form a + bi, where i = and a and b are real numbers. For example, 5 + 3i, – + 4i, 4.2 – 12i, and – – i are all complex numbers. In the complex number 6 – 4i, for example, the real part is 6 and the imaginary part is -4i.

## Is 9 a complex number?

The number 9 is in the imaginary part (9i) of this complex number. In a complex number a + bi, the real part is a. In this case, a = −35, so the real part is −35. The number 9 is in the imaginary part (9i) of this complex number.

## Is zero a complex number?

The real numbers are a subset of the complex numbers, so zero is by definition a complex number ( and a real number, of course; just as a fraction is a rational number and a real number). If we define a pure real number as a complex number whose imaginary component is 0i, then 0 is a pure real number.

## How do you know if a root is complex or real?

Real numbers have no imaginary part, and pure imaginary numbers have no real part. For example, if x = 7 is one root of the polynomial, this root is considered both real and complex because it can be rewritten as x = 7 + 0i (the imaginary part is 0).

## Why do complex roots come in pairs?

When a polynomial does not contain non-real coefficients, it does not change when we replace by . However, if it has complex roots, those roots would change. This means that taking the conjugate of the roots must result in the same set — hence, the roots must come in conjugate pairs.

## How do you explain complex concepts?

8 simple ideas for concept development and explanationUnderstand your audience. Define your terms. Classify and divide your concept into ‘chunks’ Compare and contrast. Tell a story or give an example to illustrate the process or concept. Illustrate with examples. Show Causes or Effects. Compare new concepts to familiar ones.

## How can I make complex?

A complex sentence is formed by adding one or more subordinate (dependent) clauses to the main (independent) clause using conjunctions and/or relative pronouns. A clause is a simple sentence. Simple sentences contain only one clause (verb group). Complex sentences contain more than one clause (verb group).
