Ariel completes the square for the equation x2 - 16x + 17 = 0. which of the following equations reveals the vertex of the parabola? a. y = (x - 4)^2 - 47 b. y = (x - 9)^2 - 47 c. y = (x - 6)^2 - 45 d. y = (x - 8)^2 - 47

Option D is correct

Step-by-step explanation:

A quadratic equation is in the form of ,

then the vertex form of the quadratic equation using the completing square method is given as:

where, vertex = (h, k)

As per the statement:

Ariel completes the square for the equation:

Using completing square method:

1.

subtract 17 from both sides we have;

2.

Complete the square on the left side of the equation and balance this by adding to the right side of the equation.

then;

Using identity rules on left side:

then;

we can write this as:

Therefore, the equations reveals the vertex of the parabola is,
