In the expression x + 4 + 5, you would typically follow the order of operations, which tells you to add from left to right. The associative property says that you don't have to add x and 4 first.

Drag and drop the parts of the expression into the boxes to use the associative property to create an expression in which 4 and 5 are added first. Do not change the order of the addends.

Solve for x by completing the square. 2x^2-4x+7=0
