Question

factoorise x^2-2x+1​

Answer 1

Answer:

(x - 1 )(x - 1 ) =

(x−1)2

Step-by-step explanation:

to factor #x^2 - 2x - 1 we require 2 numbers that multiply to give +1 and sum to -2. These can only be -1 , -1

since (-1) . (-1) = +1

and -1 + (-1) = -2

Answer 2

Answer:

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

= x^2 -1x -1x +1

= x ( x -1) -1 ( x-1)

= (x - 1) ( x -1)
