(x^2)/3 + (5x^2)/2 = -34
(1/3)x^2 + (5/2)x^2 = -34
(2/6)x^2 + (15/6)x^2 = -34
(17/6)x^2 + 34 = 0
(2.8333333)x^2 + 34 = 0
---
the above quadratic equation is in standard form, with a=2.8333333, b=0, and c=34
---
to solve the quadratic equation, by using the quadratic formula, copy and paste this:
2.8333333 0 34

this quadratic has two complex roots (they are NOT the x-intercepts).
the complex roots are:
x = 0 + (3.46410164)i
x = 0 - (3.46410164)i
