please help me with this question​

Answer 1

Answer:

(−1)(+1)(3−1) ok it's your answer

Answer 2

Step-by-step explanation:

Solution-:

$→⚘✯$

⚘

Given expression is -:✅

• →x3 - x2 - 4x + 4

✯☞ We have to Factorise-:

→✯We see that for x=1,The expression will be and hence,

$x - 1$

• ✯☞is a factor of the given expression

Now,✯☞x³-x²-4x+4

• ✯☞=x³-x²-4n+4
• ✯☞=x²(x-1) -4(x-1)
• ✯☞=(x-1) (x²-4)=(x-1) (x+2) (x-2)

Hence, we finally get (x-1) (x+2) (x-2)

$=x³-x²-4n+4 \\ =x²(x-1) -4(x-1) \\ =(x-1) (x²-4)=(x-1) (x+2) (x-2)$

Required answer:- ✅

• $(x-1) (x+2) (x-2). \\ ⚘$
