# Write a quadratic equation that has two imaginary solutions

Go Quadratic Equations Solving equations is the central theme of algebra. Methods for solving cubic equations appear in The Nine Chapters on the Mathematical Arta Chinese mathematical text compiled around the 2nd century BC and commented on by Liu Hui in the 3rd century.

## How can you use a discriminant to write an equation that has two solutions

Some others like T. In an early paper, he discovered that a cubic equation can have more than one solution and stated that it cannot be solved using compass and straightedge constructions. He also found a geometric solution. However, he gave one example of a cubic equation: He used what would later be known as the " Ruffini - Horner method" to numerically approximate the root of a cubic equation.

He also used the concepts of maxima and minima of curves in order to solve cubic equations which may not have positive solutions. In fact, all cubic equations can be reduced to this form if we allow m and n to be negative, but negative numbers were not known to him at that time.

Del Ferro kept his achievement secret until just before his death, when he told his student Antonio Fiore about it.

He was soon challenged by Fiore, which led to a famous contest between the two. Each contestant had to put up a certain amount of money and to propose a number of problems for his rival to solve.

Whoever solved more problems within 30 days would get all the money.

Later, Tartaglia was persuaded by Gerolamo Cardano — to reveal his secret for solving cubic equations. InTartaglia did so only on the condition that Cardano would never reveal it and that if he did write a book about cubics, he would give Tartaglia time to publish. Nevertheless, this led to a challenge to Cardano by Tartaglia, which Cardano denied. Ferrari did better than Tartaglia in the competition, and Tartaglia lost both his prestige and income. He even included a calculation with these complex numbers in Ars Magna, but he did not really understand it.

Rafael Bombelli studied this issue in detail  and is therefore often considered as the discoverer of complex numbers. Stationary point The critical points of a function are those values of x where the slope of the function is zero.In algebra, a cubic function is a function of the form = + + +in which a is nonzero..

Setting f(x) = 0 produces a cubic equation of the form + + + = The solutions of this equation are called roots of the polynomial f(x).If all of the coefficients a, b, c, and d of the cubic equation are real numbers, then it has at least one real root (this is true for all odd degree polynomials).

Anywhere you read you will learn that when you calculate the discriminant (the expression inside the square root) and if it is greater than 0 then you have two solutions, when it is equal to 0 than you have two equal solutions, but if it is less than 0 then there are no solutions among real heartoftexashop.com (We will discuss projectile motion using parametric equations here in the Parametric Equations section.).
