Geometrical (Graphical) Meaning of the Zeroes of a Polynomial Class 10th

Introduction We know that if a polynomial is p(x) and R is it’s zero then p(R) = 0. It means zeroes of every polynomial satisfy it. Let’s understand this with the help of geometrical or graphical representation. In class 10th, We shall study the geometrical representation of linear polynomial, quadratic polynomial, cubic polynomial, and also …

Linear Equations in One Variable Class 8th

Introduction We are familiar with algebraic expressions and equations because we have already studied these in the previous class. Algebraic expressions are the mathematical expressions that have the combination of numbers and the English alphabet letters. In the equations, there is the equality sign (=) that is not used in algebraic expressions. Some examples of …

Relationship Between Zeroes and Coefficients of a Quadratic Polynomial Class 10th

Introduction We use the standard form of a quadratic polynomial to find the Relationship between Zeroes and Coefficients of a Quadratic Polynomial. We know the standard form of quadratic polynomial is f(x) = ax2 + bx + c. Derivation of Formula Let α and β are the two zeroes of this polynomial. Then (x – α) …

Division Algorithm, Remainder Theorem, and Factor Theorem Class 10th

Introduction Division Algorithm, Remainder Theorem, and Factor Theorem all the three are related to Algebra. These three represent the relationship between the two functions. Division Algorithm If p(x) and g(x) are two such polynomials that the degree of p(x) is greater than g(x) and g(x) ≠ 0, and we divide p(x) by g(x) then we get …
