Can someone help me know how to do this problem In finding what I can put in for (c) in order to get 2 imaginary solutions

To get 2 imaginary solutions, c must be less than -2

Step-by-step explanation:

The general form of the quadratic equation is:

Solve the quadratic equation by using the formula:

The equation to solve is:

In our equation: a=-2, b=4, c=unknown

For the roots to be imaginary, the argument of the square root must be negative, that is:

Substituting the known values:

Subtracting 16:

Solving:

Thus, to get 2 imaginary solutions, c must be less than -2

answer:

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
