Answer:
r^2 + 10r + 4
Explanation:
To simplify the expression 4 + 10r + r^2, we can combine like terms and arrange the terms in descending order of the variable's exponent.
The expression is already in this form, so we can simply rewrite it as:
r^2 + 10r + 4
Therefore, the simplified form of the expression 4 + 10r + r^2 is r^2 + 10r + 4.
