Factoring and Simplifying Expressions

The video tutorial explains how to simplify expressions involving two variables by factoring both the numerator and the denominator. It demonstrates the process of extracting common factors and simplifying the expression by canceling out these factors. The tutorial also highlights the importance of maintaining algebraic equivalence by considering constraints, such as ensuring that certain expressions do not equal zero.

What is the first step in simplifying an expression with a non-one coefficient on the second degree term?

• Add a constant to the expression

• Factor out the greatest common divisor

• Divide the expression by a constant

• Multiply all terms by a variable

What is the result of factoring out a common factor from the numerator?

• The expression becomes a constant

• The expression is rewritten with a common factor

• The expression is simplified to a single term

• The expression is divided by zero

When factoring the denominator, what should the expressions multiply to?

• The constant term

• The sum of the coefficients

• The term with the highest degree

• The product of the leading coefficients

How do you determine the expressions to factor in the denominator?

• By finding expressions that multiply to the constant term and add to the middle term

• By finding expressions that add to the constant term

• By finding expressions that multiply to the leading coefficient

• By finding expressions that divide evenly into the numerator

In the context of factoring, what is the significance of writing expressions in terms of one variable?

• It eliminates the need for coefficients

• It allows for easier comparison and factoring

• It simplifies the expression to a constant

• It changes the degree of the polynomial
