Best ResponseYou've already chosen the best response.1when given a set of roots: {r1,r2,r3,...,rn} you can set up a poly by subtracting x from each root: (r1x)(r2x)(r3x)...(rnx)

Best ResponseYou've already chosen the best response.1or \[x=\frac{b\pm\sqrt{b^24ac}}{2a}\] \[x=\frac{3\pm\sqrt{3}}{1}\] a = 1/2 b = 3 94c = 3 c = 6/4 \[\frac12x^23x+\frac64\] \[2x^212x+6\]
