When δ 0, the equation has two equal real roots.

When δ 0, the equation has two equal real roots.

When δ 0, the equation has no real roots, but has 2 conjugate complex roots.

Variants: complex deltas.

Detailed explanation: delta is the fourth Greek letter.

The pronunciation of is δ uppercase and δ lowercase. Capitalized δ in mathematics or physics is used to denote incremental symbols. And lowercase is usually in advanced mathematics.

It is used to represent variables or symbols.

Uppercase for δ and lowercase for δ.

delta is the pronunciation of the fourth Greek letter, Chinese delta, which is capitalized as δ and lowercase as δ. Capitalized δ in mathematics or physics is used to denote incremental symbols. Lowercase δ is often used in higher mathematics to represent variables or symbols.

delta is the English word for delta, derived from the delta shaped like a triangle, like a capital delta.

Letter meaning

1. In chemistry, the covalent bond formed by the quadruple overlapping of two d orbitals is called a δ bond, which can be abbreviated as "face to face". From the point of view of the key axis, the orbital symmetry of the δ bond is no different from that of the d orbital, and the Greek letter δ is also ** in the d orbital. Indicates that it is electrified:

It means negatively charged, and δ+ means positively charged.

2. In mathematics, science, and engineering technology, it is used to express the "amount of variable bending" of a certain quantity. For example:

q = cmδt (where q represents heat, c represents the specific heat [capacity] of the substance, m represents the mass of the substance, and δt represents the amount of change in temperature).

f=k·δx (Hooke's law) (where f represents the tensile force and k represents the stiffness coefficient of the spring (or the stubbornness coefficient, and δx represents the elongation of the spring).

3. In algebra, it represents a discriminant expression of a polynomial equation or a polynomial function. The discriminant equation ax2+bx+c=0(a≠0) or the quadratic function y=ax2+bx+c(a≠0) is δ=b2-4ac.

delta (uppercase δ, lowercase δ) is the fourth Greek letter.

Uppercase δ used for: Stir the spirit.

In mathematics and science, it represents the change of variables.

In mathematics, in regression analysis, the difference between the measured value (true or accurate) and the value according to the regression equation.

In the unary quadratic equation ax2+bx+c=0(a≠0) or the quadratic function y=ax2+bx+c(a≠0) represents b2-4ac, in the equation, if δ 0, then the equation has a real solution (if δ> 0, then the equation has two unequal real solutions; If δ=0, then the equation has two equal real solutions), and if δ> 0, the image has two intersections with the x-axis; If δ=0, there is only one intersection between the image and the x-axis; If δ< 0, the image has no intersection with the x-axis.

In physics, the amount of change in a physical quantity is described.

For example, q=cmδt

where q represents the heat, c represents the specific heat [capacity] of the substance, m represents the mass of the substance, and δt represents the amount of change in temperature).

Another example is f=kδx (Hooke's law).

where f is the tensile force, k is the spring stiffness (stubbornness) coefficient, and δx is the spring elongation).

In mathematics, the triangle is delta, the pronunciation of the fourth Greek letter, which is capitalized as δ and lowercase as δ. Capitalized δ in mathematics or physics is used to denote incremental symbols. Lowercase δ is often used in higher mathematics to represent variables or symbols.

In algebra, δ used as a discriminant expression to represent the root of a quadratic equation. i.e. δ = b -4ac.

The discriminant formula of the root is a formula for judging the number of real roots of the equation, which is widely used in solving problems, involving the range of the value of the solution coefficient, the number and distribution of the number of roots of the equation, etc. The discriminant formula for the root of the unary quadratic equation ax 2+bx+c=0(a≠0) is b 2-4ac, denoted by " " (pronounced "delta").

b 2-4ac should be calculated with plus or minus signs.

It is the discriminant formula of the unary quadratic equation, which is δ=b 2-4ac after the unary quadratic equation is reduced to the general formal degree, that is, ax 2+bx+c=0.

Derivation process: The formula for finding the root of a quadratic equation is: (-b b under the root number b 2-4ac) to remove the dry code with 2a

If a quadratic equation has a real root age, then the inner equation under the root sign should be greater than zero. Therefore, b 2-4ac is called the discriminant formula, and the relationship between the magnitude and 0 determines whether Fang Rongcheng has a real root.
