First step is to separate the terms with variables from the constant terms.
Add 13 to both sides of the equation :
Divide both sides by 6 :
Next step, completing the square by adding this term to both sides of the equation :
From the equation,
a = 1
b = 16
So it follows that :
Adding this to both sides of the equation :
And you will get a perfect square trinomial on the left side of the equation in the form :
It can be factored as :
So the equation will be :
The answer is :
