Algebra Formulas
What is the Formula for a2 – b2 in Algebra?
The formula for a2– b2 defined in algebra is
a2– b2 = (a+b)(a-b)
This formula is also called the difference of squares formula.
What are Algebraic Expressions?
Algebraic expressions are combinations of variables and constants using arithmetic operations such as Addition, Subtraction, Multiplication, and Division.
Example: 11 x3 + 5x is an algebraic expression. This expression has two terms 11 x3 and 5x.
What are the Three Basic Algebra Formulas?
The three basic formulas of Algebra are:
- (a + b)2 = a2 + b2 + 2ab
- (a – b)2 = a2 + b2 – 2ab
- (a + b)(a – b) = a2 – b2
Write the Simplified Form of (a+b)².
(a+b)² can be written in simplified form as (a²+ 2ab + b²)
Algebra Formulas
Algebra Formulas are the basic formulas that are used to simplify algebraic expressions. Algebraic Formulas form the basis for solving various complex problems. Algebraic Formulas help solve algebraic equations, quadratic equations, polynomials, trigonometry equations, probability questions, and others.
An identity is a true equation for any values assigned to the variables. Algebraic Identities are used to solve various equations. For Algebraic Identities, L.H.S is always equal to R.H.S.
