To simplify the expression \( x(x^2 + 9) \), you can distribute \( x \) across the terms inside the parentheses:
\[
x(x^2 + 9) = x \cdot x^2 + x \cdot 9 = x^3 + 9x
\]
Thus, the expression \( x(x^2 + 9) \) is equal to:
\[
x^3 + 9x
\]
\[
x(x^2 + 9) = x \cdot x^2 + x \cdot 9 = x^3 + 9x
\]
Thus, the expression \( x(x^2 + 9) \) is equal to:
\[
x^3 + 9x
\]
