Given:

(x+9)^2

To find:

The given expression as a trinomial in standard form.

Solution:

We have,

(x+9)^2

Using the formula, (a+b)^2=a^2+2ab+b^2, we get

(x+9)^2=x^2+2(x)(9)+(9)^2

(x+9)^2=x^2+18x+81

Standard form a trinomial is ax^2+bx+c.

x^2+18x+81 is in the standard form.

Therefore, the required expression is x^2+18x+81.
