Dividing rational expressions

The video tutorial covers dividing rational expressions by changing the divisor to its reciprocal and simplifying the expression before performing operations. It explains factoring techniques, converting division problems to multiplication, and simplifying expressions using multiplication and division. The tutorial concludes with final simplification steps and a summary of the process.

What is the first step when dividing rational expressions?

• Add the expressions

• Change the divisor to its reciprocal

• Subtract the expressions

• Multiply the expressions directly

Which of the following is a common technique used to simplify expressions?

• Factoring trinomials

• Multiplying by zero

• Adding terms

• Subtracting terms

When factoring the expression X^2 - 6X - 27, what are the factors?

• (X + 9)(X + 3)

• (X - 9)(X + 3)

• (X - 9)(X - 3)

• (X - 3)(X + 9)

What is the result of simplifying X^2 / 2X?

• X^2

• 1/2

• 2X

• X/2

What is the simplified form of the expression X + 3 * X divided by 2 * X - 5?

• (X + 3) / (2X - 5)

• (X + 3) * (X - 5)

• (X + 3) * (2X - 5)

• (X - 3) / (2X + 5)
