Plz solve the abv question
and get urself marked as brainliest​

Answer 1

Answer:

(x^2 - 4^x) (x^2 -4x-1)-20

=(x^2–4x)(x^2–4^x−1)−20

=(x^2–4^x)2−(x^2–4^x)−20

=(x^2–4^x)2–2⋅(x^2–4^x)⋅12+14−20−14

=(x^2–4^x−12)2−(92)2

=(x^2–4^x−12+92)(x^2–4^x−12−92)

=(x^2–4^x−5)(x^2–4x+4)

=(x−5)(x+1)(x−2)2

Answer 2

Answer:

(x-5) (x+1) (x+2) (x+2)
