# Quick Answer: What Is Algebra Formula?

## What is the formula of algebraic expression?

The standard algebraic identities are: (x + a)(x + b) = x2 + (a + b) x + ab.

(a + b + c)2 = a2 + b2 + c2 + 2ab + 2bc + 2ca.

(a + b)3 = a3 + b3 + 3ab (a + b) (a – b)3 = a3 – b3 – 3ab (a – b).

## What exactly is algebra?

Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols. In elementary algebra, those symbols (today written as Latin and Greek letters) represent quantities without fixed values, known as variables. … The letters x and y represent the areas of the fields.

## Who is the No 1 mathematician in the world?

Leonhard Euler (1707- 1783) When he went blind in his late 50s his productivity in many areas increased. His famous formula eiπ + 1 = 0, where e is the mathematical constant sometimes known as Euler’s number and i is the square root of minus one, is widely considered the most beautiful in mathematics.

## What are the basics of algebra?

Basic Of AlgebraBasics of Algebra cover the simple operation of mathematics like addition, subtraction, multiplication, and division involving both constant as well as variables. For example, x+10 = 0. … Q 1: Find y, when, y + 15 = 30.Solution: y = 30 – 15.Q 2 : Find x, when, 9x = 63.Q. 3: If x/7 = 21, then find x.

## What is an example of algebra?

For example, 2(3 + 8) is a numeric expression. Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression.

## Who invented math?

Beginning in the 6th century BC with the Pythagoreans, the Ancient Greeks began a systematic study of mathematics as a subject in its own right with Greek mathematics. Around 300 BC, Euclid introduced the axiomatic method still used in mathematics today, consisting of definition, axiom, theorem, and proof.

## Who is the father of mathematics?

mathematician ArchimedesGreek mathematician Archimedes is widely considered by many to be the “father of mathematics.” He is regarded as one of the leading scientists in classical antiquity and is credited with designing numerous innovative machines, including the screw pump and siege engines.

## What is trigonometry formula?

Basic Formulas By using a right-angled triangle as a reference, the trigonometric functions or identities are derived: sin θ = Opposite Side/Hypotenuse. cos θ = Adjacent Side/Hypotenuse. tan θ = Opposite Side/Adjacent Side. sec θ = Hypotenuse/Adjacent Side.

## What is the golden rule for solving equations?

How do we apply the Golden Rule? First it should be stated, that when solving for an unknown variable in an equation, you must try to get 0 on the side with the unknown variable in addition/subtraction (and get 1 in multiplication/division).

## What are 2 step equations?

A two-step equation is an algebraic equation that takes you two steps to solve. You’ve solved the equation when you get the variable by itself, with no numbers in front of it, on one side of the equal sign.
