Question

x3+x-3×2-3
Facrorise​

Answer 1

Answer:

X^3-3X^2+X-3

= X^2(X-3)+1(X-3)

= (X-3) (X^2+1)

Step-by-step explanation:

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1:  x-3 

Group 2:  x3-3x2 

Pull out from each group separately :

Group 1:   (x-3) • (1)

Group 2:   (x-3) • (x2)

              -------------------

Add up the two groups :

              (x-3)  •  (x2+1)
