Question

(5x²y - 9xy + 7) - (3x²y + 4xy – 12)​

Answer 1

$\huge \bf \underline{ \underline{Solution}}$

= (5x²y - 9xy + 7) - (3x²y + 4xy – 12)

= 5x²y - 9xy + 7 - 3x²y - 4xy + 12

= 2x² - 13xy + 19

Final Answer:-

$\huge\mathtt{2x² - 13xy + 19}$

Answer 2

Answer:

(5x²y - 9xy + 7) - (3x²y + 4xy – 12)

5x²y-9xy+7-3x²y-4xy+12

2x²y-13xy+19
