Finding zeros of a polynomial function written in factored form

Asked by admin @ 31/10/2021 in Mathematics viewed by 326 People

The polynomial f(x) is written in factored form:

f(x) = (x − 9)(x + 12)(x − 24)
What are the zeros of the polynomial function?
A. x = −9, x = 9, x = −12, x = 12, x = −24, x = 24
B. x = −9, x = 12, x = −24
C. x = 9, x = −12, x = 24
D. x = 9, x = 12, x = 24

Answered by admin @ 31/10/2021

Answer:

Step-by-step explanation:

f(x) = (x − 9)(x + 12)(x − 24)

If f(x) =0

0 = (x − 9)(x + 12)(x − 24)

then

x-9=0 or x+12=0 or x-24=0

x=9 or x=-12 or x=24
