Rohan has ₹\((3x^2 + 5xy + 7y^2)\) in his pocket. He spent ₹ \((2x^2 + 5xy + 4y^2)\) out of it. How much money is left with Rohan?
रोहन की जेब में ₹\((3x^2 + 5xy + 7y^2)\)हैं। उसने उसमें से ₹\((2x^2 + 5xy + 4y^2)\)खर्च कर दिए। रोहन के पास कितने रुपये शेष बचे हैं?
Detailed Solution & Logic
Correct Answer:
₹\((x^2 + 3y^2)\)
Money left with Rohan:
$\left(3x^2 + 5xy + 7y^2\right) - \left(2x^2 + 5xy + 4y^2\right)$
$= 3x^2 + 5xy + 7y^2 - 2x^2 - 5xy - 4y^2$
$= x^2 + 3y^2$
Therefore, the correct answer is:
₹$\left(x^2 + 3y^2\right)$
₹\((x^2 + 3y^2)\)
