## Is there a formula to solve cubic equations?

The formula is named after Cardano, an Italian mathematician who stole the formula from somebody else. A cubic equation is an equation which can be represented in the form a x 3 + b x 2 + c x + d = 0 ax^3+bx^2+cx+d=0 ax3+bx2+cx+d=0, where a , b , c , d a,b,c,d a,b,c,d are complex numbers and a is non-zero.

What is the formula for cubic polynomial?

The cubic polynomial formula is in the general form of ax3 + bx2 + cx + d and the formula for the solution of the cubic equation is ax3 + bx2 + cx + d = 0.

### Is there a quartic formula?

There is an analogous formula for the general quartic equation, ax4 + bx3 + cx2 + dx + e = 0 . Each formula is expressible using only the operations of addition, subtrac- tion, multiplication, division, and extraction of roots.

How do you solve depression cubes?

Solving the depressed cubic. (s-t)3+3st (s-t)=s3-t3. This is true since we can simplify the left side by using the binomial formula to: (s3-3s2t+3st2-t3)+(3s2t-3st2)=s3-t3. From this, we can find a value for u by the quadratic formula, then obtain t, afterwards s and we’re done.

#### How do you break down a cubic polynomial?

Break down the sum or difference of cubes by using the factoring shortcut. Replace a with 2x and b with 3. The formula becomes [(2x) + (3)] [(2x)2 – (2x)(3) + (3)2].

What is formula of alpha and beta?

Summary. The sum of the roots α and β of a quadratic equation are: α + β = − b a \displaystyle\alpha+\beta=-\frac{b}{{a}} α+β=−ab. The product of the roots α and β is given by: α β = c a \displaystyle\alpha\beta=\frac{c}{{a}} αβ=ac.

## What is the title of Girolamo Cardano’s famous book on algebra?

The Ars Magna
The Ars Magna (The Great Art, 1545) is an important Latin-language book on algebra written by Gerolamo Cardano. It was first published in 1545 under the title Artis Magnae, Sive de Regulis Algebraicis Liber Unus (Book number one about The Great Art, or The Rules of Algebra).

What is univariate bivariate and multivariate data?

Univariate, Bivariate and Multivariate data and its analysis 1 Univariate data – This type of data consists of only one variable. 2 Bivariate data – This type of data involves two different variables. 3 Multivariate data –

### Why is the analysis of univariate data considered the simplest form?

The analysis of univariate data is thus the simplest form of analysis since the information deals with only one quantity that changes. It does not deal with causes or relationships and the main purpose of the analysis is to describe the data and find patterns that exist within it.

What is the difference between numerical data and univariate data?

With numerical data there may not be a mode or there may be too many modes. Take the family net worth example, You might have as many data points for the value $100,000 as you have for$101,000 and \$102,000, etc. Univariate data is a collection of information characterized by or depending on only one random variable.

#### What statistics are used to summarize univariate data?

The statistics used to summarize univariate data describe the data’s center and spread. There are many options for displaying such summaries. The most frequently used illustrations of univariate data are:
