\(f(3)=3^2+39=27+39=21\) \(f(3)=(3)^2+(3)9=2739=39\) \(3921=60\) now try it with just \(x\) and \(x\)

\(f(x)\) is confusing, but it means replace \(x\) everywhere by \(x\)

so first step is to write \(f(x)= (x)^3+(x)9\) and then simplify a big take that answer, and subtract \(x^3+x9\) from it make sure to use parentheses

So it would be xx9(x^2+x9)?

i assume you mean \[x^3x9(x^3+x9)\]

ok good, now remove the parentheses by distributing the minus sign, then combine like terms
