a2-3a, a2 -4a+3 এর গ সা গু কত?
Solution
Correct Answer: Option B
১ম রাশি = a2 - 3a
= a(a - 3)
২য় রাশি = a2 - 9
= a2 - 32
= (a+ 3)(a - 3)
৩য় রাশি = a2 - 4a + 3
=a2 - 3a - a + 3
= a(a - 3) - 1(a - 3)
= (a - 3) (a - 1)
নির্ণেয় গ.সা.গু = (a - 3)
= a(a - 3)
২য় রাশি = a2 - 9
= a2 - 32
= (a+ 3)(a - 3)
৩য় রাশি = a2 - 4a + 3
=a2 - 3a - a + 3
= a(a - 3) - 1(a - 3)
= (a - 3) (a - 1)
নির্ণেয় গ.সা.গু = (a - 3)
