Question

# What is this equation x2 – 2x – 6 in vertex form?

Answer

y = (x-1)^2 -7

- Identify the coefficient of x^2 A: The coefficient of x^2 is 1.
- Find the x-coordinate of the vertex using -b/2a formula A: The x coordinate of the vertex can be found using x = -b/2a formula, which is x = -(-2)/2(1) = 1.
- Substitute the value of x and simplify the equation to get the vertex form A: The vertex form of the equation is y = (x-1)^2 -7.
