Answer:

u^2 + 9

Step-by-step explanation:

you would have to put the exponent on the u and 3

so it would by u^2 + 3^2

but simplified it would be

u^2 + 9

we cannot simplify further since we don't know what u equals

By Rewrite without parentheses and simplify the given function is u^2 + 6u+ 9.

What is a system of equations?

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Given; (u+3)^2

so it would by u^2 + 3^2

(u+3)^2 =  (u+3)(u+3)

Multiply all the terms in the first parenthesis to all the terms in the 2nd parenthesis, we get;

u * u = u^2

u * 3 = 3u

3 * u = 3u

3 * 3 = 9

So we have:

u^2 + 3u+ 3u+ 9

Combine like terms:

u^2 + 6u+ 9
