Now, with complex numbers, when the Formula gives you a negative inside the root, you now can simplify that solution by using the imaginary and respond that the equation under question has no real-valued solution, but it does have a complex-valued solution. Were you to graph the quadratic ...

the roots are real and distinct, for D = 0 the roots are real and equal, and for D < 0, the roots do not exist or the roots are imaginarycomplex numbers. With the help of this discriminant and with the least calculations, we can find the nature of the roots of the quadratic equati...

where zz is a complex number and z∗z∗ is its conjugate completely separate from ordinary quadratic equations? i.e. can I use the discriminant, quadratic formula etc. If not what, what type of equation is this? Can z* be treated independently from z? How is the degree related to ...
Use the Quadratic Formula:x = −(−4) ±√(−9) 2 √(−9) = 3i (where i is the imaginary number √−1) So:x = 4± 3i 2 Answer: x = 2 ± 1.5i The graph does not cross the x-axis. That is why we ended up with complex numbers. BUT an upside-down mirror ima...
