Answer:
x³ + x² - 14x - 24.
Step-by-step explanation:
Given : (x – 4)(x² + 5x + 6).
To find : multiply.
Solution : We have given that (x – 4)(x² + 5x + 6).
Distribute the x over (x² + 5x + 6) and 4 ((x² + 5x + 6).
x (x² + 5x + 6) - 4(x² + 5x + 6).
(x³ + 5x² +6x ) -4x² - 20x - 24).
Combine like terms
x³ + 5x² - 4x² -20x +6x -24.
x³ + x² - 14x - 24.
Therefore, x³ + x² - 14x - 24.
