# How do you find all the zeros of  f(x) = (x + 3)(x – 1)(x – 5)?

Mar 16, 2016

$\left\{- 3 , 1 , 5\right\}$ are zeros of f(x)=(x+3)x-1)(x-5)

#### Explanation:

Zeros of $f \left(x\right)$ are those values of $x$, which make $f \left(x\right) = 0$.

As f(x)=(x+3)x-1)(x-5), $f \left(x\right)$ will be zero, if

x+3)=0 or x-1)=0 or $\left(x - 5\right) = 0$ i.e.

$x = - 3$ or $x = 1$ or $x = 5$

Hence, $\left\{- 3 , 1 , 5\right\}$ are zeros of f(x)=(x+3)x-1)(x-5)#
