The equation x + 2 = sqrt 3x + 10 is of the form x + a = sqrt bx + c, where a, b, and c are all positive integers and b > 1. Using this equation as a model, create own equation that has extraneous solutions.

1. Using trial and error with numbers for a, b, and c, make an equation of the form x+a = sqrt bx+ c, where a, b, and c are all positive integers and b > 1such that 7 is a solution. (Hint: Substitute 7 for x, and choose a value for a. Then square both sides so you can choose a, b, and c that will make the equation true.)
2. Solve the equation you created in Part 2a.
3. If your solution in Part 2b did not have an extraneous solution, revise your equation so that 7 is one solution and there is an extraneous solution. If your solution in Part 2b did have an extraneous solution, create another equation with different values of a, b, and c that also has 7 as one solution and an extraneous solution.
