I defined x as a syms, then work with polynomials involving x. But then I can't find an evaluation command for these polynomials at some x value. Anyone knows how I can get it to work? Thank you in advance. There's another system where you can define polynomials just like matrices, e.g. x^2+1...

For those who don't want to waste their time, the only other solution for this problem is 5.8+2.15+2*3.55=15.05 2.15 2.75 3.35 3.55 4.2 5.8 Needs 15.05 I scrutinized the combinations. It only applies to this problem. 1st, notice that, because 15.05 has a .05 in the end, we need an odd...
