How many years before the company has a profit of 0 ? F(x) =-2x^2+92x+84

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

a = 11 : 4

b = 38

c = 1 for every 6
