Question

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.

Explanation / Answer

(37-11x)=9-x, (37-11x)2=92-x2 this type squaring is wrong we square whole left hand side as well right hand side .

Square on both sides

((37-11x))2=(9-x)2

B) if u check above equations the some value substitute on the equation equation we can get both sides are equal (that equation is correct . the correct equation is

((37-11x))2=(9-x)2

C)(25)1/2=5
