Sir, i am stuck on this question only need an answer no need of an explanation

(2 marks) Consider the integral 29 dont unders I = I 2 - 8x + 41 Using "completing the square" method x2 - 8x +41 = A+ (x -k)2 ime we have where A = Number and k = Number For this kind of integral we usually use the substitution r - k = Rsinht or one is cald O r- k =Rcost ( x - k =Rtant () z - k=Rsect () r - k =Rsint () r - k= Rcosht where R = Number > 0. The above substitution z - k = Rsinht leads to an integral of the form I = B cosh t dt We have al where B = Number and p = Number s no steps
