Hello sir i want to know the best solution of the question from exercise 2.5 of math of Polynomials chapter of class 9th give me the best and easy for solving this question how i solve it of question no.8(5) Factorise each of the following:(v) 27p3–(1/216)−(9/2) p2+(1/4)p

The expression, 27p3–(1/216)−(9/2) p2+(1/4)p
can be written as (3p)3–(1/6)3–3(3p)2(1/6)+3(3p)(1/6)2
27p3–(1/216)−(9/2) p2+(1/4)p =
(3p)3–(1/6)3–3(3p)2(1/6)+3(3p)(1/6)2
= (3p–16)3
= (3p–16)(3p–16)(3p–16)
