Example From Chapter 14 Factorisation
| Ques. Factorise the expression 14pq + 35pqr Soln: 14pq + 35pqr Expressing the terms as factors 14pq = 2 × 7 × p × q 35pqr = 5 × 7 × p × q × r Therefore, The two terms have 7, p and q as common factors. Therefore, combining we get 14pq + 35pqr = 7 × p × q × 2 + 7 × p × q × 5 × r = 7 × p × q × [2 + (5 × r)] Grouping the terms, we get, = 7pq × (2 + 5r) = 7pq(2 + 5r) |
