x2-y2, (x+y)2, x3+y3 এর গ.সা.গু কত?
Solution
Correct Answer: Option B
১ম রাশি = x2 - y2
= (x + y)(x - y)
২য় রাশি =(x + y)2
=(x + y)(x + y)
৩য় রাশি =x3 + y3
= (x + y)(x2 - xy + y2)
∴ গ.সা.গু = x + y
= (x + y)(x - y)
২য় রাশি =(x + y)2
=(x + y)(x + y)
৩য় রাশি =x3 + y3
= (x + y)(x2 - xy + y2)
∴ গ.সা.গু = x + y
