Can anyone rewrite quadratic function in standard form?

Quadratic function in standard form should be f (x) = a (x-h) ^2+k

hey I believe standard form would look like this: f (x) = a (x - h) ^2 + k

this is regular form f (x) = ax^2+bx+c or something like x^2+4x+4.

I think H and K are the vertex

hope this is close to what your looking for.

Step-by-step explanation:

I think it's x^2+6x-18
