# What are the zeros of the polynomial functionf(x)=(x+6)(x+8)(x+15)?

$x = - 6 , - 8 , - 15$

#### Explanation:

We can set $f \left(x\right) = 0$, then the 3 quantities can each be set to 0:

$f \left(x\right) = 0 = \left(x + 6\right) \left(x + 8\right) \left(x + 15\right)$

and so we can find the 0's:

$\left(x + 6\right) = 0$
$x = - 6$

$\left(x + 8\right) = 0$
$x = - 8$

$\left(x + 15\right) = 0$
$x = - 15$
