Find all the values of x in the set of complex numbers that satisfy the following equation:[tex]\boxed{\sum^{\lceil \int^{\frac{\pi}{4}}_02secxdx\rceil }_{k=\lfloor \int^2_0lnxdx\rfloor}(\frac{d}{dx}(x^{k+2}))=-\lceil lim_{a\to\infty}\int_{-a}^a\frac{1}{x^2+1}dx\rceil!+1}[/tex]
a fairly standard cubic. Incidentally, when [tex]x=-2[/tex], the LHS reduces to 0, so [tex]x+2[/tex] is a factor of the cubic. You can find the remaining two solutions easily with the quadratic formula.
