Approximate the real zeros of f(x)=2x^4-x^3+x-2 to the nearest tenth. a. , 1 c. 0, 1 b. , d. , 0 select the best answer from the choices provided

ANSWER

-1.0, 1.0

EXPLANATION

The given polynomial function is



According to the Rational Roots Theorem, the possible roots of this function are;



We now use the Remainnder Theorem to obtain;









But;





Since f(1)=0 and f(-1)=0, the real zeros to the nearest tenth are:

-1.0 and 1.0
