Which equations have no real solution but have two complex solutions?

equations have no real solution but have two complex solutions When  discriminant is negative.

Step-by-step explanation:

The quadratic equation ha 2 solution

let a, b and c are the coefficients of equation.

These 2 solutions are based on the value of discriminant,

discriminant = square root (b^2 - 4ac)

If b^2 - 4ac  is a negative value we cannot find its root.

The square root of a negative number is complex number.

Therefore equations have no real solution but have two complex solutions

there are no answer choices

step-by-step explanation:

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
