Question:উৎপাদকে বিশ্লেষণ কর: `a^3 - 6a^2 + 12a - 9`
Answer `a^3 - 6a^2 + 12a - 9` `= a^3 - 6a^2 + 12a - 8 - 1` `= a^3 - 3.a^2.2 + 3.a.2^2 - 2^3 - 1` `= (a - 2)^3 - 1` `= (a - 2)^3 - (1)^3` `= (a - 2 - 1) {(a - 2)^2 + (a - 2).1 + 1^2}` `= (a - 3) (a^2 - 4a + 4 + a - 2 + 1)` `= (a - 3) (a^2 - 3a + 3)` (Ans)
