8.6 Solve Rational Equations Essential Question: How do we solve rational equations? Mastery demonstrated in writing in summary of notes and in practice problems.

Solving Rational Equations To solve a rational equation, we use methods learned earlier. Sometimes we will cross multiply and sometimes we will factor to find the LCD. When we have multiple solutions, we should check for extraneous solutions.

Example 1 (Cross multiply.)

Example 2

Example 3

Example 4 (Find the LCD.)

Example 5 (Find the LCD and check for extraneous solutions.)

Example 6

Example 7

Summary: EQ: How do we solve rational equations? Be sure to write 2-3 complete sentences. Don’t forget your 3 questions too!
