Answer:
(x-1)(x-1)
Step-by-step explanation:
hello :
(x+2) ²-6 (x+ 2) +9 =(x+2) ²-2×(<em>3</em>) (x+ 2) +<em>3²</em>
by identity : (a-b)² = a²-2ab+b²
let : a=x+2 and b= <em>3</em>
(x+2) ²-6 (x+ 2) +9 =(x+2) ²-2×(<em>3</em>) (x+ 2) +<em>3²=</em> ((<em>x+2)-3</em>)<em>²= (</em>x+2-3)² = (x-1)²=
(x-1)(x-1)
