Which method is used to factor an expression with only two terms?

• Quadratic formula

• Binomial theorem

• Product-sum table

• GCF

What does the 'magic pair' refer to in the context of factoring by the product-sum table?

• The pair of terms that can be factored no further

• The initial pair of terms in the expression

• The pair of factors that sum up to the middle term

• The pair of highest common factors

What is the purpose of eliminating common factors in the context of simplifying expressions?

• To determine the GCF

• To expand the expression further

• To simplify the expression to its lowest terms

• To identify the product-sum table

Why is it important to understand excluded values in rational expressions?

• To make the expression easier to graph

• To avoid division by zero in the expression

• To ensure the expression is defined for all real numbers

• To simplify the expression correctly
