What is the first step in converting a quadratic equation from standard form to vertex form?

• Divide all terms by the coefficient of x squared

• Move the constant term to the other side

• Square the x term

• Factorize the equation

What does completing the square help to identify in a quadratic equation?

• The y-intercept

• The maximum value

• The x-intercepts

• The vertex of the parabola

What is the vertex form of a quadratic equation?

• a(x-h)^2 + k

• (x + h)(x + k)

• ax^2 + bx + c

• ax^2 - bx - c

What is the significance of the vertex in the context of a quadratic equation?

• It indicates the highest or lowest point on the graph

• It represents the x-intercept of the graph

• It is where the graph crosses the y-axis

• It determines the slope of the graph

What indicates an irrational solution when completing the square?

• A non-perfect square under the square root

• A negative number under the square root
