Answer:
The zeros are 4 and -6
Step-by-step explanation:
f (x) = x^2 + 2x − 24
Start by factoring so the equation looks like this: f(x) = (x + _)(x - _)
When you factor, you need to find two numbers that add to the middle term and multiply to equal the last term.
Two numbers that work are -4 and 6.
-4 + 6 = 2 (so that works for the middle term) and -4 * 6 = -24 (that works for the last term)
When you put those numbers in the parentheses, it looks like this:
f(x) = (x + 6)(x - 4)
Make both equal to 0 and solve for x: x + 6 = 0, x - 4 = 0
x = -6, x = 4
