Determine the nature of roots of the following quadratic equation.
Activity : \(m^2 + 2m + 9 = 0\)
\(a = \) ____ , \(b = 2\), \(c = 9\)
\(b^2 - 4ac = 2^2 - 4 \times 1 \times \) ____
\(= \) ____ \(- 36\)
\(\therefore b^2 - 4ac = \) ____
\(\therefore b^2 - 4ac \lt 0\)
\(\therefore\) Roots of quadratic equation are not real.
