Question

Which algebraic expression means “three more than a number squared”?
2 n + 3
2 n minus 3
n squared + 3
n squared minus 3

Answer 1

The phrase “three more than a number squared” can be translated into an algebraic expression as follows:

- "a number" can be represented by \( n \).
- "squared" means raising that number to the power of 2, represented as \( n^2 \).
- "three more than" means adding 3 to that squared number.

Putting it together, the expression becomes:

\[
n^2 + 3
\]

So, the correct answer is **n squared + 3**.
