Ok so can you please tell me where I go wrong here. I want to put(adsbygoogle = window.adsbygoogle || []).push({});

y=3x^2+2x-1 into y=a(x-h)^2+K

ax^2-2ah+ah^2+k=3x^2-2x+ah^2-1

ax^2=3x^2 -----> a=3

-2ahx=-2x

-2(3)hx=-2x ----->h=1/3

K=----->-1

Therefore:

y=3(x-1/3)^2-1

But I think it's suppost to be: y=3(x+1/3)^2-4/3

Is that right??? So what is wrong....
