If we express 3x^2-6x-2 in the form a(x-h)^2+k what is a+h+k
Thanks this one confused me
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!
no -7 didn't work can you tell me how to complete it please?
