1. Question: `(x^2 - 9)/(ax + 3a)` এর লঘিষ্ট রুপ নিচের কোনটি?

    A
    `(x + 3)/a`

    B
    `a/(x + 3)`

    C
    `(x - 3)/a`

    D
    `a/(x - 3)`

    Note: `(x^2 - 9)/(ax + 3a)` `= (x^2 - 3^2)/(a(x + 3)` `= ((x + 3) (x - 3))/(a(x + 3))` `= (x - 3)/a`

  2. Question: `a^2/(a + b)` `b^2/(a + b)`

    A
    a + b

    B
    a - b

    C
    `1/(a + b)`

    D
    `1/(a - b)`

    Note: `a^2/(a + b) - b^2/(a + b)` `= (a^2 - b^2)/(a + b)` `= ((a + b) (a - b))/(a + b)` `= a - b`

    B
    `x^3 - 8`

    C
    `x^3 + 8`

    D
    `(x - 2)^2`

    Note: ভগ্নাংশগুলোর হরগুলোর ল,সা,গু,ই সাধারণ হর।
