Mastering Multiplication and Simplification of Rational Expressions

What is the first step when multiplying rational expressions?

• Adding the expressions

• Simplifying the expressions

• Factoring each part

• Finding the restrictions

What does the 'and' symbol represent in the context of multiplying rational expressions?

• Division

• Multiplication

• Subtraction

• Addition

When factoring x^2 - 4, what are the factors?

• x + 2 and x - 2

• x + 4 and x - 4

• x - 2 and x - 2

• x + 2 and x + 2

Which common factor can be canceled out in the expression (x^2 - 4) / (x^2 - 1) * (x + 1) / (x^2 + 2x)?

• x - 2

• x + 1

• x + 2

• x - 1

What is the restriction for the variable when x + 1 is in the denominator?

• x ≠ 2

• x ≠ 0

• x ≠ -1

• x ≠ 1

In Example B, what are the factors of 3x^2 + 5x - 2?

• 3x - 2 and x + 1

• 3x - 1 and x + 2

• 3x + 2 and x - 1

• 3x + 1 and x - 2

What is the restriction for the variable when 3x - 1 is in the denominator?

• x ≠ -3

• x ≠ 1/3

• x ≠ -1/3

• x ≠ 3

What is the simplified form of the expression (3x^2 + 5x - 2) / (x - 5) * (x^2 - 25) / (3x^2 - 7x + 2)?

• (x - 5) / (x + 5)

• (x + 5) / (x - 5)

• (x - 2) / (x + 2)

• (x + 2) / (x - 2)

What is the restriction for the variable when x - 2 is in the denominator?

• x ≠ -2

• x ≠ 0

• x ≠ 2

• x ≠ 1
