Answer:
That is a quadratic equation.
It can be solved by using the quadratic formula:
x = (-b +-sqr root b^2 -4*a*c) / 2 *a
In this equation a = -3
b = -4 and c = -8
x = (--4 +- sqr root (-4^2 - 4 * -3 * -8)) / (2 * -3)
x = (4 +- sqr root (16 -96)) / -6
x = 4 +- sqr root (-80) / -6
x1 = (4 +8.94427191 * i) / -6
x2 =(4 -8.94427191 * i) / -6
Remember that "i" is the square root of minus 1.
