Answer

x = 0 Explanation 1. Factor the expression Factor out the greatest common factor x^2: f(x) = x^2(x^2 + 1). 2. Set each factor to zero Solve x^2 = 0 and x^2 + 1 = 0 separately. 3. Solve x^2 = 0 x = 0. 4. Solve x^2 + 1 = 0 x^2 = -1, which has no real solutions.

Explanation

1. Factor the expression<br /> Factor out the greatest common factor $x^2$: $f(x) = x^2(x^2 + 1)$.<br />2. Set each factor to zero<br /> Solve $x^2 = 0$ and $x^2 + 1 = 0$ separately.<br />3. Solve $x^2 = 0$<br /> $x = 0$.<br />4. Solve $x^2 + 1 = 0$<br /> $x^2 = -1$, which has no real solutions.
