Algebraic and transcendental equations; Algebraic equations: Every algebraic equation of degree n ≥ 1 has a root real or comple..

Trinomial is a polynomial consist of three terms in algebra. These Expression is made up of constants, variables, exponents which are combined using addition, subtraction and multiplicati..

Function in algebra is defined as a relation f , which associates to each element if set A, a unique element b of set B, is a function from set A to a set ..

Fundamentals of Equations Algebraic and transcendental equations; If f(x) is a polynomial in x, then f(x) =0 is an algebraic equation. Example; x 7 + 5x - 2=0. If f(x) contains algebraic and non algebraic functions namely exponential, logarithmic, t..

A solution of a linear equation is the value of the variable which makes LHS = RHS. It is also called the "root" of the equation. To solve a linear equation , we transpose all the terms containing the variable to one side and the constant terms to the other. The equation then reduces to th..

In algebra we come across certain products very frequently. For e.g., (a + b) 2 , (a + b) 3 (a + b + c) 2 etc. These are nothing but products of binomials or trinomials. We derive the formulae for these products and apply them whenever necessary. These expansions help us to avoid elab..

An equation of one variable and of first order (i.e., its highest power is one) is called a linear equation . Such an equation has only one solution. A solution is also called the 'root' of the given equatio..
