The video tutorial covers solving quadratic equations by factoring. It begins with an introduction to quadratics, explaining that they involve variables raised to the second power. The zero product property is introduced, which states that if the product of two factors is zero, then at least one of the factors must be zero. The tutorial demonstrates how to factor quadratic equations and solve them using this property. Advanced techniques for factoring more complex quadratics are also discussed, along with a final example and tips for successful factoring.

Why should you not divide both sides of a quadratic equation by a variable?

• It makes the equation unbalanced

• It changes the solutions

• It loses one of the solutions

• It makes the equation more complex

What should you do if a quadratic equation does not equal zero?

• Multiply both sides by a constant

• Move all terms to one side to make it equal zero
