Answer 1

please check if it is correct or not

Answer 2

Answer:

Step-by-step explanation:

(x^2-2x)^2-23(x^2-2x)+120

let a=x^2-2x

a^2 - 23a +120

a^2-15a-8a+120

a(a-15) - 8(a-15)

(a-15) (a-8)

(x^2-2x-15) (x^2-2x-8)

(x^2+3x-5x-15) (x^2-4x+2x-8)

(x(x+3)-5(x+3)) (x(x-4)+2(x-4))

(x+3) (x-5) (x-4) (x+2)

hope it helps
