Answer:

[tex]x^{2} -6x+9[/tex]

Step-by-step explanation:

This binomial can be solved by the perfect square binomial method. Its standard form is:

[tex](a-b)^{2}  = a^{2} -2ab+b^{2}[/tex]

In this way, substituting

[tex]a=x;    b=3[/tex]

[tex](x-3)^{2}  = x^{2} -2(x)(3)+(3)^{2}  = x^{2} -6x+9[/tex]
