Preeti Dabral 4 years, 6 months ago

Given that x³− 2x²− x+2

= x³ − x− 2x² +2

Grouping the 1st 2 terms together and the 2nd 2 together:

= x(x²− 1) − 2(x² − 1)

= (x²− 1) (x−2)

Using the identity: a² − b²= (a+b) (a−b)

= (x²−12) (x−2)

= (x−1) (x+1) (x−2)

27 - 125a³ - 135a + 225a²
= (3)³ - (5a)³ - 3(3)(5a)(3 - 5a)
= (3 - 5a)³
(Using Identity (a – b)³= a³– b³– 3ab (a – b))
= (3 - 5a)(3 - 5a)(3 - 5a)
