Consider a sequence F00 defined as:

F_0{_0} (0) = 1, F_0{_0} (1) = 1,

F_0{_0}(n)=\frac{10*F_0{_0}(n-1) + 100}{F_0{_0}(n-2)}

Demo question

2=\frac{b^2-4ac}{4a^2}

(x+\frac{b}{2a})^2=\frac{b^2-4ac}{4a^2}

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

 

x^2+px+q=0

\sin^2\theta + \frac{b}{\sqrt {ac}} \sin\theta \cos\theta \pm \cos^2\theta = 0
