(4x2 - 16) এবং (6x2 + 24x + 24) এর গ.সা.গু-
Solution
Correct Answer: Option D
১ম রাশি = 4x2 - 16
= 4(x2 - 4)
= 4(x2 - 22)
= 4(x + 2)(x - 2)
২য় রাশি = 6x2 + 24x + 24
= 6(x2 + 4x + 4)
= 6(x2 + 2.x.2 + 22)
= 6(x + 2)2
= 6(x + 2)(x + 2)
(4x2 - 16) এবং (6x2 + 24x + 24) এর গ.সা.গু = 2(x + 2)
= 4(x2 - 4)
= 4(x2 - 22)
= 4(x + 2)(x - 2)
২য় রাশি = 6x2 + 24x + 24
= 6(x2 + 4x + 4)
= 6(x2 + 2.x.2 + 22)
= 6(x + 2)2
= 6(x + 2)(x + 2)
(4x2 - 16) এবং (6x2 + 24x + 24) এর গ.সা.গু = 2(x + 2)
