complex numbers – What is the solution to the equation below?

Multiplying both sides by $(x+9)^2$ yields
$$(x^2+18x+162)x^2=40(x^2+18x+81)$$
which is equivalent to
$$x^4+18x^3+122x^2-720x-3240=0$$
Factorization gives
$$x^4+18x^3+122x^2-720x-3240=(x^2+20x+180)(x^2-2x-18)$$
Which has roots, given by the quadratic formula,
$1+\sqrt{19},1-\sqrt{19},-10+i\sqrt{80},-10-i\sqrt{80}$$
