Respuesta :

ANSWER:

[tex](y-6)^2=8(x+2)[/tex]

STEP-BY-STEP EXPLANATION:

We have the following equation

[tex]y^2-12y-8x+20=0[/tex]

We convert it to its vertex form like this:

[tex]\begin{gathered} 8x=y^2-12y+20 \\ \text{ we complete square} \\ 8x=y^2-12y+20+(-6)^2-(-6)^2 \\ 8x=(y-6)^2-16 \\ 8x+16=(y-6)^2 \\ (y-6)^2=8(x+2) \end{gathered}[/tex]
