Question

The sum of two expression is 19x²y² - 4xy +15. If one expression is x² y² + 3x-9, find the other.

Answer 1

Answer:

18x²-4xy-3x+24

Step-by-step explanation:

Let the other expression be 'expression '

x² y² + 3x-9 + expression = 19x²y² - 4xy +15

expression = ( 19x²y² - 4xy +15 ) - ( x² y² + 3x-9 )

= 19x²y² - 4xy +15 - x² y² - 3x+9

= 19x²y² -x² y² - 4xy -3x+9 + 15

Ans = 18x²-4xy-3x+24
