Math Problem Statement
Factorise the following
Factorise: (i) x^3 - 2x^2 - x + 2 (ii) x^3 - 3x^2 - 9x - 5 (iii) x^3 + 13x^2 + 32x + 20 (iv) 2y^3 + y^2 - 2y - 1
Solution
To factorize the given polynomials, we need to find the factors that multiply to give the original expressions. Let's start by examining each polynomial one by one:
(i)
