Transfer an equation from standard form to vertex form

The video tutorial explains how to transform an equation from standard form to vertex form by completing the square. It begins with an introduction to the standard and vertex forms of a quadratic equation. The process of completing the square is detailed, including factoring and adjusting terms. The tutorial then demonstrates transforming the equation into vertex form and identifying the vertex from the transformed equation.

What is the standard form of a quadratic equation?

• Y = ax + b

• Y = ax^2 + bx + c

• Y = a(x - h)^2 + k

• Y = a(x + h)^2 - k

Why is it necessary to factor out the coefficient of x^2 when completing the square?

• To simplify the equation

• To ensure the equation is in the correct form for completing the square

• To eliminate the constant term

• To make the equation linear

What is the next step after factoring out the coefficient in completing the square?

• Multiply the equation by the coefficient

• Calculate (b/2)^2 and add it to the equation

• Divide the entire equation by the coefficient

• Add the constant term to both sides

How do you transform the expression inside the parentheses into a perfect square?

• By multiplying by the coefficient

• By rearranging the terms

• By dividing by the coefficient

• By adding and subtracting the same number

What is the vertex of the equation y = 2(x - 1)^2 - 4?

• (2, -4)

• (1, 4)

• (-1, 4)

• (1, -4)
