Answer:
Factors are (x-1) (4x²-1)
Zero(s) are x = 1, x = 1/2, x = -1/2
Explanation:
Given function is
4x³ - 4x² - x + 1
= 4x³ - x - 4x² + 1
= x(4x² - 1) - 1(4x² - 1)
= (x - 1) (4x² - 1) (Factors of the equation)
To find the zero(s),
Either, Or,
x - 1 = 0 4x² - 1 = 0
or, x = 1 or, x² = 1/4
or, x = √(1/4)
or, x = +- 1/2
