Answer:
The zeros are 4, -6, and 1.
Explanation:
Given f(x) = x³ + x² - 26x + 24
(x - 4) is a factor of f(x). That means it is a zero of f(x).
To find the remaining factors algebraically, we take out the factor (x - 4) from f(x).
That is,


Taking
out, we have:

Taking (x - 4) common out, we have:




This means the zeros are 4, -6, & 1.
