Just solve for t using factorization:
t² - t - 6 = 0
(t - 3) (t +2) = 0
so t = 3 or t = -2

I assume you want to find t
you have t^2 + t - 6 = 2t
make the right side 0 by subtracting 2t from both sides.
then you have
t^2 - t - 6 = 0
factor it...
(t-3) (t+2) = 0
you know what? t-3 = 0 or t+2 = 0
then solve for t!

t² + t - 6 = 2t
t² + t - 6 - t = 2t - t
t² - 6 = t
t² - 6 - t = t - t
t² - t - 6 = 0
(t - 3)(t + 2)
(t - 3)(t + 2) = t² - 3t + 2t - 6 = t² - t - 6
The answer is x = 3 and x = - 2
Insert the x value into the equation
- - - - - - - - - - - - - - - - - - - - - - -
Check
x = 3
t² + t - 6 = 2t
(3)² + 3 - 6 = 2(3)
9 + 3 - 6 = 6
12 - 6 = 6
6 = 6
- - - - - - - - - - - - -
Check
x = - 2
t² + t - 6 = 2t
(- 2)² + (- 2) - 6 = 2(- 2)
4 - 2 - 6 = - 4
4 - 8 = - 4
- 4 = - 4
- - - - - - - - - - - - -
Roots
t = 3
t = - 2

t² - t - 6 = 0
now factor it to:
(t + 2)*(t - 3) = 0
one or both of the expressions in parenthesis must be zero to make the entire expression true so:
(t + 2) = 0 and/or (t - 3) = 0
t = -2 and/or t = 3
so t = -2 and/or 3

hmm, thats only one variable, t, right? If so, subtract 2t from both sides.
t² - t - 6 = 0
Then factor.
(t - 3)(t + 2)=0
That means t can either equal 3 or -2.

t^2 + t - 6 = 2t
t^2 - 6 = t
t^2 = t + 6
t = sqrt(t + 6)

if a/b=c/d, then ad=bc here, x^2+2x=15 so x^2+2x-15=0 (x-3)(x+5)=0 then,x=3 & x=-5 God bless you.
