 Hi and how are you all today? Let us discuss this question, it says write the general term in the expansion of x square minus y the whole raised to the power 6. Now we must know first of all how do we write the general term of r plus one-eth term that is ncr e raised to the power n minus r v raised to the power r. Now the knowledge of this general term is the key idea of a question the solution says the general term of tr plus one is written as ncr a raised to the power n minus r v raised to the power r and we are given x square minus y raised to the power 6. First of all we can write it as x square plus minus y the whole raised to the power 6 right. Now here on comparing it with the general term that we explained in the key idea a is equal to x square b is equal to minus y and n is equal to 6. On substituting the values of abn in the formula that is mentioned in the key idea we have tr plus one is equal to 6cr a that is x square n minus r b that is minus y raised to the power r that is it can be written as minus one raised to the power r 6cr multiplied by x raised to the power. Now this two has been multiplied with 6 and then with r and can be written as 12 minus 2r getting multiplied by y raised to the power r. So this becomes the answer of the section. I hope you understood the question do remember the general term of the binomial expansion as it will be useful if on many of your solutions. Take care.
