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:-
[tex]t^{2}-15=0[/tex]
[tex] t^{2} =15[/tex]
[tex]t = \sqrt{15} [/tex] or [tex]t = -\sqrt{15} [/tex]
So the roots or zeros are - [tex] \sqrt{15}[/tex] and [tex] -\sqrt{15} [/tex]
t² - 15 = 0
⇒ t² = 15
⇒ t = √15 and -√15
