Best ResponseYou've already chosen the best response.0\(f(3)=3^2+39=27+39=21\) \(f(3)=(3)^2+(3)9=2739=39\) \(3921=60\) now try it with just \(x\) and \(x\)

Best ResponseYou've already chosen the best response.0\(f(x)\) is confusing, but it means replace \(x\) everywhere by \(x\)

Best ResponseYou've already chosen the best response.0so 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

Best ResponseYou've already chosen the best response.0So it would be xx9(x^2+x9)?

Best ResponseYou've already chosen the best response.0i assume you mean \[x^3x9(x^3+x9)\]

Best ResponseYou've already chosen the best response.0ok good, now remove the parentheses by distributing the minus sign, then combine like terms
