Solving a trigonometric equation for purely imaginary numbers

$f(x),g(x)$,2 quadratic polynomials:$|f(x)|≥|g(x)|∀x ∈ R$. Find the number of distinct roots of equation $h(x)h''(x)+(h'(x))^2=0$ if $h(x)=f(x)g(x)$

number of solutions of $f(f(f(f(x))))$

How do I find integers $x,y,z$ such that $x+y=1-z$ and $x^3+y^3=1-z^2$?
