Answer :

Let


Putting


Where t=x2


t2=A(t+9)(t+16)+B(t+1)(t+16)+C(t+1)(t+9)


Now put t+1=0


t=-1


A(8)(15)+B(0)+C(0)=1



Now put t+9=0


t=-9


A(-9+9)(-9+16)+B(-9+1)(-9+16)+C(-9+1)(-9+9)=(-9)2


A(0)+B(-56)+C(0)=81



Now put t+16=0


t=-16


A(0)+B(0)+C(-15)(-7)=(-16)2


A(0)+B(0)+C(105)=256



From equation(1)
