put 5x²+49 =t to get,

12.5¹⁵âˆ« (t-49)¹⁴t¹⁷ dt . t=49->âˆž

=> expanding by binomial theorum and integrating we get

=> 12.5¹⁵ (-14_C₀.t^-22 + 14_C₁.49.t^-33 -...........)

=> now putting limits and using limit t->âˆž t^-k = 0

=> also we get (49)^-2 common in each term,

=> 12.5¹⁵.49² Î£ 14_C_r(-1)^rr+2

u cn do it frm here
