Given that f : x -> x^2 + 6x, and g: x -> 2x - 1 ... where x is a real number.
Find the two values of x such that fg(x) = gf(x), giving each answer in the form
I have tried solving it by equating by solving it for both of the functions but that's not working. How should I proceed with it?
Sorry, but I should have posted the steps. I just wanted to know if I had to right idea. Ok, so far my steps were correct but at the last step, I was finding this using quadratic formula.
The answer I am supposed to get is but I am getting . I had, similarly, tried it without simplification at the last step ... can't seem to figure out what's wrong.
