Simple way, remember this quadratic formula: x = (-b+-√b²-4ac) / 2a
a - 2 = 3/3+6a
(a-2) (3+6a) = 3
3a + 6a² - 6 - 12a = 3
6a² - 9a - 6 - 3 = 0
6a² - 9a - 9 = 0
a=6 b=9 c=9
Note that a² is a. a is b. 9 is c. That is the quadratic formula.
We will use the quadratic formula here:
x = (-b+-√b²-4ac) / 2a
Note that you have to use + / - separately to get the correct answer.
x = (-9+√9²-4 (6) (-9) / 2 (6) = 0.68
x = (-9-√3²-4 (6) (-9)) / 2 (6) = - 2.18
So the value of a is either 0.68 or - 2.18.

Here-
Let's solve your equation step-by-step.
Step 1: Simplify both sides of the equation. a-2 = 3/3 + 6a
Simplify:a + - 2 = 1 + 6a
a - 2 = 6a + 1
Step 2:
Subtract 6a from both sides.
a-2 - 6a = 6a + 1 - 6 a
-5a-2=1
Step 3: Add 2 to both sides.
-5a-2 + 2 = 1 + 2
-5a = 3
Step 4: Divide both sides by - 5.-5a / - 5 = 3/-5
Final Result:
a = - 3/5
