Answer:
Discriminant = 49
Step-by-step explanation:
d = b^2 - 4ac = (1)^2 - 4 * 1 * (-12) = 1 + 48 = 49

_______________________
[tex] {x}^{2} + x - 12 = 0 \\ \\ a = 1 \\ b = 1 \\ c = - 12 \\ \\ \boxed{ \fbox{ \green{ \mathfrak{discriminant = {b}^{2} - 4ac}}}}[/tex]
[tex] {1}^{2} - 4 \times 1 \times - 12 \\ = > 1 +48\\ = > 49 \\ 49 < 0[/tex]
which is smaller then 0,
so,this equation have 2 real roots.
