# Thread: Solve in C

1. ## Solve in C

Solve in C
$
z^{3}+\sqrt{z}+1=0
$

2. Hint : put $\sqrt{z} = u$ ,and solve $u^6+u+1$.

3. let y = x^3 + x^(1/2) + 1; for x should not be less than 0.
Plotting it, we have

No real roots i think.

he said solve in C,not in R
because if he said solve in R,and since $z\geq 0$ there will be no solutions.
