Explain how to determine the zeros of f(x)=(x+3)(x-1)(x-8)

Solution :  x = -3, x = 1 , x = 8,

Steps : 1) Set f ( x ) = 0.

2) Set each factor equal to zero and solve to find the x- intercepts.

Step-by-step explanation:

Given : f(x)=(x+3)(x-1)(x-8).

To find : how to determine the zeros .

Solution : We have given that : f(x)=(x+3)(x-1)(x-8).

Steps for finding zeros

1) Set f ( x ) = 0.

2) Set each factor equal to zero and solve to find the x- intercepts.

Set f(x) = 0

(x+3)(x-1)(x-8) = 0

Now each factor equal to zero

(x+3) = 0

On subtracting by 3 both sides

x = -3

(x-1) = 0

On adding by 1 both side.

x = 1.

(x-8) = 0.

On adding by 8 both side.

x = 8.

Therefore, Solution :  x = -3, x = 1 , x = 8,

Steps : 1) Set f ( x ) = 0.

2) Set each factor equal to zero and solve to find the x- intercepts.

yeah. here's some.
