as a trinomial in standard form.
Answer
Attempt 1 out of 2

Answer 1

To express the expression as a trinomial in standard form, we need to expand the squared term.

(x-7)^2 can be expanded as (x-7)(x-7), which equals x^2 - 7x - 7x + 49.
Combining like terms, we get x^2 - 14x + 49.

So the trinomial in standard form is x^2 - 14x + 49.
