Question:
` 1/(x + 2) - 1/(x - 2) + 4/(x^2 + 4)` এর মান কত?
A
`2 - (32)/(x^2 - 8)`
B
`- (32)/(x^4 - 16)`
C
`(32)/(x^4 - 16)`
D
`(32)/(x^4 + 16)`
Note:
`(x - 2 - x - 2)/((x + 2) (x - 2)) + 4/(x^2 + 4)` `= (- 4)/(x^2 - 4) + 4/(x^2 + 4)` `= (- 4x^2 - 16 + 4x^2 - 16)/((x^2 - 4) (x^2 + 4))` `= (- 32)/(x^4 - 16)`

Question:
`(a^2 - 4b^2)/(a + 2b)` এর লঘিষ্ট আকার নিচের কোনটি?
A
a - 2b
B
a - 3b
C
a + 4b
D
a + 2b
Note:
`(a^2 - 4b^2)/(a + 2b)` `= (a^2 - (2b)^2/(a + 2b)` `= ((a + 2b) (a - 2b))/(a + 2b)` `= a - 2b`
