How to find the x intercepts (solutions) of a quadratic in vertex form

The video tutorial explains how to find the X intercepts of a quadratic equation by setting y=0. It contrasts solving quadratics in standard form, which requires factoring, with solving in vertex form, which uses reverse operations. The tutorial outlines the steps to solve quadratics in vertex form, including undoing addition, subtraction, multiplication, and division, and taking the square root of both sides. The process concludes with finding the X intercepts and expressing them as coordinate points.

What is the first step in finding the X-intercept of a quadratic equation?

• Set y to zero

• Factor the equation

• Multiply both sides by zero

• Add a constant to both sides

What is the advantage of using the vertex form of a quadratic equation?

• It simplifies the equation

• It requires factoring

• It eliminates the need for factoring

• It uses complex numbers

Which operation should be undone first when solving a quadratic equation in vertex form?

• Square Root

• Division

• Addition or Subtraction

• Multiplication

What must be introduced when taking the square root of both sides of a quadratic equation?

• A variable

• Plus or minus sign

• A constant

• A coefficient

How can the X-intercepts be expressed after solving the quadratic equation?

• As coordinate points

• As a decimal

• As a single number

• As a fraction
