Misty Charnesky—Week 7 DQ 2 DQ 2: From your reading in section 10.6, describe a step-by-step process to solve radical equations. List each step and provide an explanation of how to complete each step with an example. The steps to solving a radical equation are simple: 1. Isolate the radical term 2. Use the principle of powers 3. If a radical still remains do step 1 and 2 again 4. Factor 5. Principle of zero products 6. Check + + - = x 5 x 5 10 first we have to isolate the radical + = - + x 5 x 5 10 radical is isolated + =( - + ) … x 52 x 5 10 2 use the principle of powers + = - + - + …. x 5 x 5 20x 5 100
