Is there a simple (i.e. without using of op( ), coeff( ), etc.)  way to force Maple to put a common constant out of brackets in the expression like 2*a+2*b -> 2(a+b)? The task seems as very simple. But I can't find a solution

Hello!

Is there any chance to bring the expression x²+xy+y² to the form like x²+y²+xy (i.e. to set/define exact order of monomials) with Maple? What syntax (i.e. commands, packages, etc.) should I use? Many thaks in advance for any useful advice
