Question

How do you find the zeros of `x^2-4x-12`?

Answer 1

Factor the expression, if possible.
`x = -2` and `x = 6`

Explanation:

The "zeros" of the expression are found in one method by creating a simpler set of factors and then finding the zeros of those parts.
There are other tutorials online that explain the factoring process in more detail. For this example:
`x^2 − 4x − 12 = (x +2)xx(x - 6)`

Setting each of these factors to zero we obtain:
`(x +2) = 0`; `x = -2` AND
`(x - 6) = 0`; `x = 6` are zeros of the function.
