Simplify two rational expression by adding

The video tutorial explains how to add rational expressions by finding common denominators. It emphasizes the importance of common denominators and provides a step-by-step example using the fractions 2/3 and 1/4. The tutorial demonstrates how to multiply denominators to find a common denominator and highlights the process of simplifying expressions through factoring and the distributive property. The video concludes with a final simplification of the expression, ensuring a clear understanding of the process.

What is the first step in adding rational expressions?

• Divide the fractions

• Subtract the denominators

• Find a common denominator

• Multiply the numerators

In the example of adding 2/3 and 1/4, what is the common denominator used?

• 16

• 12

• 8

• 6

Why is it not always necessary to find the least common denominator?

• It takes too much time

• It is not mathematically correct

• Any common denominator will work

• It is too complicated

What is the purpose of factoring in the simplification process?

• To simplify the expression

• To change the expression completely

• To make the expression more complex

• To increase the value of the expression

What happens to the eights in the final simplification step?

• They cancel out

• They are divided

• They are added together

• They are multiplied
