You haven't written RHS value of the equation. I think you forgotten to write 0 in RHS.
Assuming that RHS is 0
we have the equation:-
t^{2}-15=0
 t^{2} =15
t =  \sqrt{15} or t = -\sqrt{15}
So the roots or zeros are -  \sqrt{15} and  -\sqrt{15}
1 5 1
hope you find it helpful.,..... please mark as best

T² - 15 = 0
⇒ t² = 15
⇒ t = √15 and -√15
0
