ncert.nic.in• The factorisation done by using the distributive law (property) is called the common factor method of factorisation. • Sometimes, many of the expressions to be factorised are of the form or can be put in the form: a2 + 2ab + b2, a2 – 2ab + b2, a2 – b2 or x2 + (a + b) x + ab. These expressions can be easily factorised

www.ncert.nic.inthe factorisation of 1 188 the prime 2 appears only two times and the prime 1 1 appears once. So, if we divide 1188 by 2 × 2 × 11 = 44, then the prime factorisation of the quotient will not contain 2 and 1 1. Hence the smallest natural number by which 1 188 should be divided to make it a

www.mathsaulycee.sitew.comFactorisation de polynômes de degré 3 Théorème(admis) Si un polynôme P de degré 3 admet une racine réelle fi, alors ce polynôme est factorisable par (x¡fi). on a alors : P(x) ˘(x¡fi)£Q(x) où Q(x) est un polynôme de degré 2. Utilisation: Le polynôme P(x) ˘x3 ¡4x2 ¡7x¯10 admet comme racine évidente le nombre 1.
