Hey: ) can you me posted picture of question

x² - 5x - 24

Explanation:
To answer this question, we will multiply each term from the first bracket by each term from the second bracket and then we will combine like terms to get the final expression.

This can be done as follows:
(x - 8)(x + 3)
x(x) + x(3) - 8(x) - 8(3)
x² + 3x - 8x - 24
x² - 5x - 24

Hope this helps :)
