Given the equation 3x2 − 18x + 15 = 0, what are the values of h and k when the equation is written in vertex form a(x − h)2 + k = 0?

h = 3, k = −12
h = 3, k = 3
h = −3, k = 27
h = −3, k = −27

h = 3, k = −12

Step-by-step explanation:

We have the following expression:

For this case we can take a common factor for example 3 and we got this:

Then we can complete the square like this:

So then if we compare we got

So then the best option is:

h = 3, k = −12
