What do I need to know to multiply and divide rational expressions

The video tutorial explains how to multiply and divide rational expressions, emphasizing the importance of understanding regular fractions. It highlights the need for factoring to simplify expressions and avoid complex polynomials. The tutorial stresses simplifying expressions before and after operations and clarifies the division property, which applies only when terms are separated by multiplication. The video concludes with a summary of key points.

What is the first step in multiplying fractions?

• Add the numerators

• Multiply straight across

• Divide the denominators

• Subtract the numerators

How can division of fractions be rewritten?

• As subtraction of the divisor

• As addition of the divisor

• As multiplication of the reciprocal of the divisor

• As division of the reciprocal of the divisor

Why is factoring important when multiplying rational expressions?

• To increase the size of polynomials

• To simplify expressions before multiplying

• To add more terms to the expression

• To avoid using the reciprocal

When can the division property be applied?

• When terms are separated by division

• When terms are separated by addition

• When terms are separated by subtraction

• When terms are separated by multiplication

What should be done after multiplying or dividing rational expressions?

• Simplify the expression further

• Divide by the largest term

• Multiply by the reciprocal

• Add more terms
