how many real solutions are there to the equation shown below?
x^2+2x+6=0
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To answer this question, calculate the discriminant of the equation
d = b^2 - 4ac, referring to the general form ax^2 + bx + c = 0.
The discriminant is
d = 2^2 - 4*1*6 = 4 - 24 = -20.
The discriminant is negative - - - so, this equation has no real solutions.
ANSWER. The number of real solutions is 0 (zero).
Solved.
It is how such questions should be treated.
