Question 916820

{{{y = a(x - h)^2 + k}}}

To convert an equation from the form {{{y = ax^2 + bx + c}}} into the form {{{y = a(x - h)^2 + k}}} use completing the square.

What does the equation {{{y = 3x^2 -18x + 34}}} become after completing the square?


{{{y = 3x^2 -18x + 34}}} 

{{{y = 3x^2 -18x + 27+7)}}} 

{{{y = (3x^2 -18x + 27)+7)}}}
 
{{{y=3(x^2-6x+9)+7}}}

{{{y=3(x-3)^2+7}}}
