Question

What are the zeros of the polynomial function y = (x - 3)(2x + 1)(x - 1)? A. 1/2, 1, 3 B. -1, 1, 3 C. -1/2, 1, 3 D. -3, 1/2, -1

Answer 1

x=3 x = -1/2 x=1

Explanation:

y = (x - 3)(2x + 1)(x - 1)

Set the function equal to zero

0 = (x - 3)(2x + 1)(x - 1)

Using the zero product property

x-3 =0 2x+1 =0 x-1 =0

x=3 2x = -1 x=1

x=3 x = -1/2 x=1
