Answer:

f(x) = 11x^2 + 12x - 12

g(x) = 12x^2 - 11x + 11

find g(f(3))

I'm not sure if i did everything correct, I came up with g(f(3)):31,734. I'd just like to know if this is right, and if not I'd like to see the steps so I know what I did wrong, thank you!

Answer:

$x^6+3x^3+3+\dfrac{1}{x^3}$

Step-by-step explanation:

We can use the pascal triangle to find the coefficients of the expasion of the cube. It holds that

$(x^2 + \dfrac{1}{x})^3=(x^2)^3+3(x^2)^2\dfrac{1}{x}+3x^2(\dfrac{1}{x})^2+(\dfrac{1}{x})^3\\\\=x^6+3x^4\dfrac{1}{x}+3x^2\dfrac{1}{x^2}+\dfrac{1}{x^3}\\\\=x^6+3x^3+3+\dfrac{1}{x^3}$
