Can these ternary expression with expensive method calls be simplified without outline variables ...

I do NOT want to - call expensive methods more than once. - make "outline" temporary variables. Outline variables are ones declared outside ternary expressions. - leak variables with letters.

var out1 = ExpensiveMethod1(x, y) is bool __ ? __.ToString() : "null";
var out2 = ExpensiveMethod2(x, y) is bool ___ ? ___.ToString() : "null";
var out3 = ExpensiveMethod3(x, y) is bool ____ ? ____.ToString() : "null";

var out1 = ExpensiveMethod1(x, y) is bool __ ? __.ToString() : "null";
var out2 = ExpensiveMethod2(x, y) is bool ___ ? ___.ToString() : "null";
var out3 = ExpensiveMethod3(x, y) is bool ____ ? ____.ToString() : "null";

where bool? ExpensiveMethod*<T,U>(T t, U u){}. Can these expression be simplified even further?

not enough information what do those methods return? conditional access operator and null coalescing operator var out1 = ExpensiveMethod1(x, y)?.ToString() ?? "null";
