Determine how many, what type, and find the roots for f(x) = x3 - 4x2 – 16x + 64.
SHOW WORK!

x=4

Step-by-step explanation:

x^3-4x^2-16x+64

(x^2-16)(x-4)

x-4=0

 +4  +4

x=4

x^2-16=0

    +16   +16

x^2=16

√ x^2=√ 16

x=4

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.
