Question

factorise x³-2x²-x+2​

Answer 1

Answer:

Factorise x³-2x²-x+2→

x³-2x²-x+2

=> x²(x-2)-1(x-2)

=> (x²-1)(x-2)

(1 can be Expressed as 1²)

=> (x²-1²)(x-2)

(a²-b² = (a+b)(a-b))

=> (x+1)(x-1)(x-2)

The factors of x³-2x²-x+2 are→

(x+1)(x-1)(x-2)

Answer 2

$\huge {\underline {\purple {\bigstar {\boxed{answer}}}}}$

$= {x}^{3} - 2 {x}^{2} - x + 2$

$\red{= > {x}^{2} (x - 2) - 1(x - 2)}$

$= > \green{ ({x}^{2} - 1)(x - 2)}$

so, the answer is

$\orange ☞ \huge {\underline {\fcolorbox {pink}{blue}{(x2 - 1)(x - 2)}}}$
