→ When an algebraic expression can be written as the product of two or more expressions is called a factor of the given expression and this process of finding factors is called factorisation.
→ An irreducible factor is a factor which cannot be expressed further as a product of factors.
→ Factorisation when a conimon monomial factor occurs in each term:
→ Factorisation by grouping:
→ Factorisation when a binomial is common:
→ Factorisation by using formulae:
→ A monomial multiplied by a monomial always gives a monomial. But a monomial divided by a monomial may not give a monomial.
→ If the remainder is zero, both the divisor and the quotient, are factors of the dividend.
→ In case of divisions of algebraic expressions, we have Dividend = Divisor × Quotient + Remainder.
→ We know that in the case of numbers, division is the inverse of multiplication. This idea is applicable also to the division of algebraic expressions.
→ In the case of division of a polynomial by a monomial, we may carry out the divison either by dividing each term of the polynomial by the monomial or by the common factor method.
→ In the case of division of a polynomial by a polynomial, we cannot proceed by dividing each term in the dividend polynomial by the divisor polynomial. Instead, we factorise both the polynomials and cancel the common factors.
→ When you square a monomial, the co-efficient and each factor has to be squared.
