Solve: x - 1 (x - 1)² + ax - a.

Step-by-step explanation:

x-1-(x-1)²+ax-a

Factorize the expression ?

Given expression is x-1-(x-1)²+ax-a

It can be written as

(x-1)-(x-1)²+(ax-a)

=> (x-1)-(x-1)(x-1)+a(x-1)

=> (x-1)[1-(x-1)+a]

=> (x-1)(1-x+1+a)

=> (x-1)(2-x+a)

x-1-(x-1)²+ax-a = (x-1)(2-x+a)

Hope this helps!!

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
