It's already solved for x. If the left side of an equation
is " x = " and the letter x does not appear on the right side
at all, then the equation is solved for x.
Did you mean to say you were solving for t and not x, and
just mistyped?
If so, then to solve for t, then we get zero on one side
Swap sides
Subtract x from both sides:
Put parentheses around the last two terms on the left
to show that together they can be used to substitute
for c in the quadratic formula. This step may be
skipped:
Then we use the quadratic formula with

Factor 2 out of the top
Cancel the 2 in the top into the 12 on the bottom
getting 6 on the bottom:
That's really two solutions:
1. 
2.
