Simplifying Rational Expressions
Lesson 1 Rational Expressions Students will be able to simplify expressions Students will be able to multiply and divide rational expressions
Warm Up Factor. 1. 2 x 2 - 3 x + 1 2. 4 x 2 – 9 3. 5 x 2 + 6 x + 1
Key Concepts Rational Expression – the quotient of two polynomials. Simplest Form – the numerator and denominator of a rational expression have no common factor
Example 1 What is in simplest form? State restrictions on the variable.
Example 2 What is the product in simplest form? State any restrictions on the variable.
Example 3 What is the quotient in simplest form? State any restrictions on the variable.
Lesson 2 Rational Expressions Students will be able to add and subtract rational expressions
Warm Up Add or Subtract. 1. 2.
Key Concepts Steps to Add or Subtract Rational Expressions: 1. Find the LCD of the rational expressions. 2. Write each rational expression as an equivalent rational expression whose denominator is the LCD found in Step 1. 3. Add or subtract numerators, and write the result over the denominator. 4. Simplify resulting rational expression, if possible.
Example 1 What is the least common multiple (LCM) of 2 x 2 - 8 x + 8 and 15 x 2 - 60.
Example 2 What is the sum of the two rational expressions in simplest form?
Example 3 What is the difference of the two rational expressions in simplest form?
Lesson 3 Rational Expressions Students will be able to simplify complex rational expressions
Warm Up Find the least common multiple of the two numbers. 1. 7, 21 2. 6, 10 3. 11, 17
Key Concepts Complex Fraction - a fraction that has a fraction in its numerator or denominator or in both its numerator and denominator.
Example 1 What is the simplest form of the complex fraction?
Example 2 What is the simplest form of the complex fraction?
