Question

factorise each of the polynomials x^3-3x^2-x+3​

Answer 1

Answer:

x^ 3 - x - 3x^2 +3

x ( x^2 - 1 ) - 3 ( x^ 2 - 1)

(x-3) ( x^ 2 -1)

the required answer

Answer 2

Step-by-step explanation:

x^3-3x^2-x+3

x^2(x-3)-1(x-3)

(x^2-1)(x-3) =0

x^2-1=0

x^2=1

x=√1

x-3=0

x=3

x=√1,3.....Ans
