Subtract first expression FROM the second expression. Therefore, the first expression is the SUBTRAHEND; the second expression is the MINUEND.
Rule in subtraction of algebraic expression: Change the sign of each term, then proceed to addition rule.
3x² - 5x + 8y + 7xy + 2y²
+ -4x² - 2x +3y - 7xy +3y²
-x² -7x + 11y + 5y²
Arrange in descending order:
-x² + 5y² - 7x + 11y, Final Answer
