Read More →Addition and Subtraction of Polynomials Addition of polynomials means we simply add the like terms. so, what is “Like terms”? Like terms are terms that have the variables, and powers are same, and coefficients of terms can be different. Example: 1. Yes 2x, -5x, 11x, […]
Read More →Cube Root by Factorisation Method In this lesson we will learn prime factorisation of the numbers and their cubes. Before we study how to calculate cube root by prime factorisation we will see, What is prime number, prime factorisation, cube root and cube numbers. A prime number is a natural number greater than 1, with exactly two […]
