Answer by TimothyLamb(4379) (Show Source): You can put this solution on YOUR website!
2t^2 + 1 = 6t
2t^2 - 6t + 1 = 0
---
the above quadratic equation is in standard form, with a=2, b=-6, and c=1
---
from the quadratic formula the discriminant is: b^2 - 4ac
---
b^2 - 4ac
(-6)^2 - 4(2)(1)
36 - 8 = 28
---
Answer 1:
since the discriminant > 0 the function has two real roots
