Explain why the given statement is true for any numbers c and d. HINT GIVEN: Look at the properties of absolute value. sqrt[9c^2 - 18cd + 9d^2] = 3|c - d|
Explain why the given statement is true for any numbers c and d. HINT GIVEN: Look at the properties of absolute value. sqrt[9c^2 - 18cd + 9d^2] = 3|c - d|
Inside the radicand, I divided every term by 9 and reduced the trinomial to be sqrt[c^2 - 2cd + d^2]. I then factored and got (c - d)(c - d) in the radicand.
Where do I go from here?
