Question 567822
Solve for x

x(x+2)(x-2)=35805
{{{x^3 - 4x - 35805 = 0}}}
----------------
There's a method to solve cubics, but it's complex and tedious.
If I didn't know 33 was a root, I would graph it.
-----------
With a large coefficient, the 35805, and only -4 times the x term, there's likely to be a root near the cube root of 35805.
{{{root(3,35805) = 32.9595}}}, close to 33, so checking for 33 being a root is reasonable.
The other 2 roots are complex.
{{{x = -33/2 +- i*sqrt(3251)/2}}}
