+23247 'Expand' usually means that you need to use the distributive property (or an extended distributive property); for example: Expand: 6x(2x² - 4x + 7) [Answer is 12x^3 -24x² + 42x]
'Evaluate' usually means to enter values for variables and simplify to get the answer; for example: Evaluate when x = 2 and y = 5: 3xy + x - y [Answer is 27]
