Find the vertex and x intercepts of a quadratic

This video tutorial explains how to complete the square for a quadratic equation with a leading coefficient other than one. It covers the process of converting the quadratic into standard form, factoring, creating a perfect square trinomial, and solving for the vertex. The tutorial also discusses finding zeros and concludes with a note on the absence of real roots in certain cases.

What is the first step in completing the square for a quadratic equation?

• Solve for the x-intercepts

• Ensure the quadratic is in standard form

• Find the vertex of the parabola

• Determine the maximum or minimum value

Why is it important to factor out the coefficient of the squared term in a quadratic equation?

• To determine the axis of symmetry

• To simplify the equation

• To find the x-intercepts

• To create a perfect square trinomial

What is a perfect square trinomial?

• A trinomial with a constant term of zero

• A trinomial that cannot be factored

• A trinomial with three different terms

• A trinomial that can be factored into two identical binomials

How do you maintain the balance of an equation when completing the square?

• By adding and subtracting the same value on one side

• By adding the same value to both sides

• By multiplying both sides by the same value

• By subtracting the same value from both sides

What is the vertex of the quadratic equation after completing the square in this example?

• (1/2, 20)

• (1, 20)

• (0, 20)

• (1/2, 0)

Why does the quadratic equation in this example have no real roots?

• The square root of a negative number is involved

• The equation is not in standard form

• The vertex is above the x-axis

• The coefficient of x is zero

What does it mean when a graph does not cross the x-axis?

• The graph has a minimum point

• The graph is a straight line

• The graph has a maximum point

• The graph has no real roots
