    x^2+1=A(x-2)^2+B(x-2)(x-3)+C(x-3)

    You can find C pretty fast by letting x be 2

    You can find A pretty fast also by letting x be 3

    You have two unknown values which it leaves you with the one, B. You can replace A with whatever you found and replace C with whatever you found and then use any value for x besides 2 or 3 to find B
