उत्तर
If (x2y + y2 + 3) is subtracted from (3x2y + 2y2 + 5), then coefficient of y in the result is `bb(underline(2x^2))`.
Explanation:
(x2 + y2 + 3) is subtracted from (3x2y + 2y2 + 5)
= (3x2 + 2y2 + 5) – (x2y + y2 + 3)
= 3x2y + 2y2 + 5 – x2y – y2 – 3
= (3x2y – x2y) + (2y2 – y2) + (5 – 3)
= 2x2y + y2 + 2
