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

Apr 1, 2018

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:
$\left(x + 2\right) = 0$; $x = - 2$ AND
$\left(x - 6\right) = 0$; $x = 6$ are zeros of the function.
