Question:উৎপাদকে বিশ্লেষণ কর: `3(a^2 + 2a)^2 - 22(a^2 + 2a) + 40` 

Answer `3(a^2 + 2a)^2 - 22(a^2 + 2a) + 40` `= a^2 + 2a = p` `= 3p^2 - 22p + 40` `= 3p^2 - 12p - 10p + 40` `= 3p(p - 4) - 10(p - 4)` `= (p - 4) (3p - 10)` `= (a^2 + 2a - 4) {3(a^2 + 2a) - 10}` [p] `= (a^2 + 2a - 4) (3a^2 + 6a - 10)` (Ans)
