Answer:
The roots are x = -1, 1/2 and 8.
Explanation:
The roots of the polynomial, also called the zeros, solutions or x-intercepts, are the solutions to its factors. The factors of this polynomial is (2x-1) and (x-8) and (x+1). Set each factor equal to 0 and solve for x. The solutions for x are the roots.
(2x-1) = 0 so x = 1/2
(x-8) = 0 so x = 8
(x+1) = 0 so x = -1
The roots are x = -1, 1/2 and 8.
