 Question 227039: I am really struggling with this problem. Can someone please help me with it? Thank you so much! Find (f ◦ g)(1), (g ◦ f)(1), (f ◦ g)(x), and (g ◦ f)(x) where f(x) = 3x^2 + 4 and g(x) = 4x – 1 Click here to see answer by algebrapro18(206)

 Question 227096: 2X^2 -7X=9 THIS IS AN EXAMPLE OF QUADRATIC BY COMPLETING THE SQUARE I THEN GET X^2 - 7/2X = 9/2 BECAUSE I DIVIDE BY 2 TO GET X^2 - 7/2X + 49/16 = 9/2+ 49/16 TO GET (X - 7/4)^2 =121/16 WHY DOES (X-7/4)^2 = 121/16 I KNOW THAT 4 ^2 EQUALS 16 BUT HOW DID MY BOOK GET THE 121 Click here to see answer by josmiceli(9664)

 Question 227626: Okay so I understand how to factor this question 3x^2-15x-60, but do I have to factor this equation out before I use the quadratic formula? if so this is what I have 3(x^2-5x-20) my question is can you show me how to plug it into the quadratic formula?

 Question 228412: 20x^(2/3) - 6x^(1/3) - 2 = 0 I have tried using my book's suggestion to solve this problem, which is to use a variable, in this case, for (x^1/3) = m. What winds up happening is that I wind up with a factorization problem that doesn't make sense (unfortunately, the text book shows us only the SIMPLEST form of a certain type of problem, leaving you on your own when it comes time to solve something a little more challenging). I am having difficulty grasping the steps and proper execution of this problem and would greatly appreciate your help. Thank you. Click here to see answer by Theo(3458)
