Hello everyone(adsbygoogle = window.adsbygoogle || []).push({});

Here is my problem

lagrange interpolation polynomial across the points(x0,y0),(x1,y1) and (x2,y2) is given by y0L0(x) + y1L1(x) + y2L2(x)

where L0(x)=-x and L1(x)=x ^2 + x

Therefore L2(x) is given by

I tried it but i could'nt crack it
