Answer:
Explanation:
[tex](x-5)^2[/tex] is a square of an expression with two terms, meaning that we can use the imformation, [tex](a+b)^2 = a^2+2ab+b^2[/tex]
In this case, our a = x, and our b = -5
[tex]a^{2}[/tex] would simply be [tex]x^2[/tex]
our 2ab would simply be [tex]2(x)(-5)[/tex] which is -10x
And our [tex]b^2[/tex] would be [tex](-5)^2[/tex] which is 25
So that means that
[tex](x-5)^2[/tex] would be equal to [tex]x^2-10x+25[/tex] in standard form
Hope this helps.
