Answer» HEY there! Here's the solution to your question. Answer: -2x² +4XY - 3y² Step-by-step explanation: To know what should be ADDED to 3x²-5xy+4y² to obtain x²-xy+y², we have to subtract 3x²-5xy+4y² from x²-xy+y². So, 1 x² - 1 X y + 1 y² (-) 3 x² - 5 x y + 4 y² - 2x² + 4 x y - 3 y² Therefore, - 2x² +4xy - 3y² should be added to 3x²-5xy+4y² to obtain x²-xy+y².
Thanks! |
