Hi guys,

Could anyone help me on simplify this function? I wanna remove the brackets.

f(x)=(x^2 + 1)^3

Thank you

come on, you can do it yourself, or a search will do

f(x)=(x^2 + 1)*(x^2 + 1)*(x^2 + 1)

Hi,

syms f(x)
fun = f(x) == (x^2 + 1)^3
fun = collect(fun,x)

results in:

fun =

f(x) == (x^2 + 1)^3

fun =

f(x) == x^6 + 3*x^4 + 3*x^2 + 1
