6t^2+5=2t^2+1
6t^2-2t^2+5-1=0
4t^2+4=0
4(t^2-1)=0
4(t+1)(t-1)=0
t+1=0
t=-1 ans.
t-1=0
t=1 ans.

Why would you foil this?
:
Assuming the problem is
6x^2 + 5 = 2x^2 + 1
:
6x^2 - 2x^2 = -5 + 1
:
4x^2 = -4
Divide both sides by 4
x^2 = -1
x =
x = i

:
Check solution in original equation
6(i^2) + 5 = 2(i^2) + 1
We know that i^2 = -1
6(-1) + 5 = 2(-1) + 1
-6 + 5 = -2 + 1
-1 = -1
