How do I do splitting middle term easily?? |
| Answer» I will tell it with one instance .eg:- 6x square -3-7xfirstly write the polynomial correctly I.e 6x square -7x-3.Multiple the 3 with 6.Then we get 6×-3=-18.Next ,write the multiples and sums of -18.-6×3=-18 but-6+3=-3-9×2=-18 but -9+2=-7So now we got the same numbers whose multiple is -18 and sum is -7.Therefore, 6x square -9x+2x-3=3x (2x-3) 1 (2x-3)=(3x+1)(2x-3)Now we got the answer.It is very easy. | |
