U have converted the numerator and denominator. I accept it. I again accept that the 2nd, 4 th, 6th term will be same of expansion of (a+2)^6 & (a-2)^6 with different signs. Then we get 1sr term =a^6( this will be two times) 7 th term =2^6(same as above) 2 third and 2 fifth terms (3rd and 5th terms number coefficient is same as those are equidistant from the ends of expansion. ) The number coefficient pattern as follows 1, 6/1. (6*5/1*2 ) 6*5*4/1*2*3 (6*5/1*2 ) 6/1 1, Algebraic letter coefficient pattern a^6, a^5,(a^4,)a^3,(a^2,) a^1,a^0 This thinking will make the sum short and un -tiresome and speedy.
When y=x.x,then 63X6 becomes 63y4 and not 63y3.Pl.correct it and proceed further for Solution

since y>0, 63y^2+700y+720>0 , we can not find any real solutions for y.
