Question 7 of 10

This question practices expanding two positive integer brackets with larger numbers.

‹ ›

\( \begin{array}{l}\textbf{Expand and simplify the expression:} \\ (x + 10)(x + 9)\end{array} \)

Choose one option:

\( x^2 + 19x + 90 \) \( x^2 + 9x + 90 \) \( x^2 + 10x + 90 \)

Double-check the addition of x-terms after multiplying each term.

Use FOIL systematically and then combine like terms carefully to get the final simplified expression.
