Using the discriminant formula b² - 4ac, the nature of roots of the the quadratic equation can be identified.
x² + 2x + 3 = 0
a = 1; b = 2; c = 3
Discriminant = (2)² - 4 (1)(3)
= 4 - 12
= - 8
If the discriminant is < 0 or the discriminant is negative, there is no real solution because the solution is imaginary or complex number.
It also means that there is no x-intercept or the graph (parabola does not pass through x-axis. Either the minimum or maximum of the graph is below or above the x axis.
ANSWER: The nature of the roots of the given solution is NO REAL SOLUTIONS.
