Question

Write an equivalent expression standard form. B. (x-5)^2

Answer 1

Step-by-step explanation:

`(x-5)^2` is a square of an expression with two terms, meaning that we can use the imformation,
`(a+b)^2 = a^2+2ab+b^2`

In this case, our a = x, and our b = -5

`a^(2)` would simply be
`x^2`

our 2ab would simply be
`2(x)(-5)` which is -10x

And our
`b^2` would be
`(-5)^2` which is 25

So that means that

`(x-5)^2` would be equal to
`x^2-10x+25` in standard form

Hope this helps.
