Question

Dum hai to solve kro
factorise: x³-2x²-x+2
plz solve by the language and by correct method ​​

Answer 1

Answer:

x³-2x²-x+2

x²(x-2)-1(x-2)

(x-2)(x²-1)

Answer 2

Answer:

We have to find the zeroes

First use trial and error method

u can substitute 2

if u substitude 2 in x the ans will be 0

Hence (x-2) is one zero

Now divide the given equation by ( x-2)

We will get x2 - 1 as answer

On factorising it we will get

x2 - 1 ^2

we get

(x-1) and (x +1 )

so ur factors r redy
