(x - y)(y + 3) কোন রাশির উৎপাদক?
Solution
Correct Answer: Option C
(x - y)(y + 3
= x(y + 3) - y(y + 3)
= xy + 3x - y2 - 3y
= xy - y2 - 3y + 3x
∴ xy - y2 - 3y + 3x এর উৎপাদক হচ্ছে (x - y)(y + 3)
= x(y + 3) - y(y + 3)
= xy + 3x - y2 - 3y
= xy - y2 - 3y + 3x
∴ xy - y2 - 3y + 3x এর উৎপাদক হচ্ছে (x - y)(y + 3)
