Answer:
2 real solutions
Step-by-step explanation:
Since the degree of the polynomial is 2, then there are 2 solutions for the equation, but we don't know if they are both complex or both real.
Since the discriminant is 
, then there are 2 real solutions.
d = |150 - 20t|
70 = |150 = 20t|
70 = 150 - 20t -70 = 150 - 20t
-80 = -20t -220 = -20t
4 = t 11 = t
