Factoring out a GCF then factoring using various methods

The video tutorial explains how to solve equations using the difference of squares method. It begins by identifying when an equation can be expressed as a difference of squares and highlights the importance of square numbers. The tutorial then demonstrates factoring out common factors and setting the equation to zero. It further explains the zero product property to find solutions, providing a step-by-step approach to solving the equation. The video concludes by presenting the final solutions.

What is the first step when you encounter an equation that is not in the form of a difference of squares?

• Use the quadratic formula

• Add a constant to both sides

• Look for a common factor to factor out

• Multiply both sides by a constant

After factoring out the common factor, what should you do next to solve the equation?

• Set the equation equal to zero

• Add the common factor back

• Multiply the factors

• Use the quadratic formula

What is the pattern used to factor a difference of squares?

• (X + a)(X + a)

• (X + a)(X + b)

• (X + a)(X - a)

• (X - a)(X - a)

How do you verify the solutions obtained from the difference of squares?

• By graphing the equation

• By using the quadratic formula

• By substituting the solutions back into the original equation

• By checking if the product of the factors equals the original expression

What property is applied to find the solutions after factoring the equation?

• Zero product property

• Commutative property

• Distributive property

• Associative property
