Question

So for the equation 9x^2 - 24x + 16, when using quadratic formula I get the equation (x-4/3)^2, but that doesn't make any sense when checking again. The correct answer would be (3x-4)^2, but I thought quadratic formula worked for all quadratic equations. Am I doing something wrong?

Answer 1

Answer:

first off, your answer isn't wrong. all you need to do is multiply through by 3. Then you'll get the answer in the format you want.

Hope this helps
