Mathematics NCERT Grade 8, Chapter 14 Factorisation The chapter lays emphasis on the concept of how to express algebraic expressions as the products of their factors In the introduction part following topics are discussed 1 Factors of natural numbers 2 Factors of algebraic expressionsThe Factor Theorem states that if P/Q is root of a polynomial then this polynomial can be divided by q*xp Note that q and p originate from P/Q reduced to its lowest terms In our case this means that 3x 3x 2x12 can be divided by 3 different polynomials,including by x3 Polynomial Long Division 24 Polynomial Long Division Important Questions for Class 10 Maths Chapter 8 Introduction to Trigonometry Introduction to Trigonometry Class 10 Important Questions Very Short Answer (1 Mark) Question 1 If tan θ cot θ = 5, find the value of tan2θ cotθ (12)
