C.
The middle term would contain two -3x terms, which when added will give you -6x. Also, the positive 9 is due to two -3s being multiplied together

Answer:
Option C is correct
Step-by-step explanation:
Given the expression [tex](x-3)^2[/tex]. we have to simplify the given expression and choose the equivalent expression from the given options.
Expression: [tex](x-3)^2[/tex]
Using the identity
[tex](a-b)^2=a^2+b^2-2ab[/tex]
Put a=x and b=3, we get
[tex](x-3)^2=x^2+3^2-2(x)(3)[/tex]
[tex]=x^2+9-6x[/tex]
⇒ [tex](x-3)^2=x^2-6x+9[/tex]
Hence, option C is correct
