Question 171708: What type of solution do you get for quadratic equations where D < 0? Give reasons for your answer. Also provide an example of such a quadratic equation and find the solution of the equation Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! What type of solution do you get for quadratic equations where D < 0?
It does not have Real Number solutions; it has complex number solutions.
-------------------------------
Give reasons for your answer.
If b^2 - 4ac < 0 the sqrt is a complex number
----------------------------
Also provide an example of such a quadratic equation and find the solution of the equation
x^2 + 5x + 10 = 0
x = [-5 +- sqrt(25-4*10)]/2
x = [-5 +- sqrt(-15)]/2
x = [-5 +-isqrt(15)]/2
