This week is all about radical expressions and equations! Complete all three parts a) Can I square squareroot 37 - 11x = 9 - x by first squaring the 9 then squaring the x? In other words, would this be correct: (squareroot 37 - 11x)^2 = 9^2 - x^2? Why or why not? If it is incorrect, what would be the correct way? b) Why is it important to always check your proposed solution using the original equation? What type of solution may be introduced if you don't check your work? c) Simplify (25)^1/2 and explain how you got your answer.
