Question

function
f(x)= 3x^2
g(x)= 2x
solve.
(f-g)(x)

Answer 1

While both of these functions are equal to x, then we can subtract one function condition from the other. Here. Lemme show ya.

(f - g)(x)

Fill in the blanks with the given conditions:
We know that: f(x)= 3x^2.
We also know that: g(x)= 2x.
Because both functions 'agree' on 'x', we can go right ahead and substitute these conditions into: (f - g)(x).

( (3x^2) - (2x) ), while both functions 'agree' on 'x'.

This problem has no like terms that I can see, so 3x^2 - 2x can be a solution.
I would factor out the x's though, because each term shares one. So you'd really get:

x(3x - 2)

...As a result.

I think that's good and correct. I hope I helped ya out! ^_^
