Question

(x-2)²-81 factorize ​

Answer 1

$= {x}^{2} - 2 \times x \times 2 + {2}^{2} - 81 \\ = {x}^{2} - 4x + 4 - 81 \\ = {x}^{2} - 4x - 77$

hope it help you!

Answer 2

Step-by-step explanation:

let x-2=y

then y²-81

formula a²-b²=(a+b)(a-b)

(y-9) (y+9)

keep the value of y

(x-2+9)(x-2-9)

(x+7)(x-11) Answer
