Let (x^2 - 2x) = a


a^2 - 2a - 3

=> a^2 - 3a +a - 3

=> a(a-3) +1(a-3)

=> (a-3)(a+1)

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

=> [ x^2 - 3x + x +3] [ x^2 - 2x +3]

=> [ x(x-3) +1(x-3)] [ x^2-2x +3]

=> (x-3)(x+1)(x^2 - 2x+3)

Let (x^2 - 2x) = a

a^2 - 2a - 3

=> a^2 - 3a +a - 3

=> a(a-3) +1(a-3)

=> (a-3)(a+1)

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

=> [ x^2 - 3x + x +3] [ x^2 - 2x +3]

=> [ x(x-3) +1(x-3)] [ x^2-2x +3]

=> (x-3)(x+1)(x^2 - 2x+3)

hope it helped⚡
