We have the following equation:
j (x) = x2 - 12x + 7
We match zero:
x2 - 12x + 7 = 0
We pass the constant term to the right:
x2 - 12x = -7
We complete square:
(b / 2) ^ 2 = (-12/2) ^ 2 = (-6) ^ 2 = 36
x2 - 12x + 36 = -7 + 36
x2 - 12x + 36 = 29
The equation in the form of vertex is:
(x-6) ^ 2 = 29
The vertice is:
(6, -29)
Answer:
the correct vertex form is:
(x-6) ^ 2 = 29
the vertex is:
(6, -29)
