The equation x²+2x=2x+x² is a commutative property, which means the sum of x²+2x will exactly equal x²+2x.
The commutative property says that changing the order of two numbers (4 + 2; 2 + 4) does not change the sum of the numbers (6 = 6).
The closure property states that the sum of two whole numbers (say a, b) will always be a whole number (a+b).
For example, putting the value of x = 1, in x²+2x=2x+x²
1²+2(1)=2(1)+ 1²
3 = 3
Therefore, the equation x²+2x=2x+x² shows a commutative property, that is by changing the order of numbers, their sum remains the same.
