Same process as for https://web2.0calc.com/questions/the-quadratic-x-2-20x-36-can-be-written-in-the-form, except you now compare the coefficient of the x^2 term as well.

 

a(x - h)^2 + k → a(x^2 - 2hx + h^2) + k → ax^2 - 2ahx + ah^2 +k

 

coeff of x^2:   a = 3

 

coeff of x:      -2ah = -6

 

constant;      ah^2 + k = -2

 

I'll leave you to complete it!
