What is the complete factorization of x2 − 6x + 9?
A. (x + 3)2
B. (x + 1)(x − 9)
C. (x − 3)(x + 3)
D. (x − 3)2

(x-3)^2 ---d

Step-by-step explanation:

X^2-6x+9

We need two numbers whose sum is -6

Product is +9

X^2-6x+9

X^2-3x-3x+9

x(x-3)-3(x-3)

(X-3)(x-3)

(x-3)^2

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

i use my brain for prombles like this maybe you could try it
