Finally someone can explain how to get the number of imaginary roots!

[ibouto]

Helpful video! Better than the crappy Hawkes software

Thank you for explaining the imaginary or complex roots. I was lost for ever and a day on that.

Thanks man, it's really helpful.

Good review. However, Descartes Rule of Signs says nothing about whether roots are rational or irrational. Consider x^2-5=0. Also, imaginary roots are not irrational (or rational, for that matter). Irrational numbers are a subset of the real numbers.

OMG thanku soooo much, i understood the whole sign process, but i didnt know how to do the chart thing, thank u soo much I finally get it

[keybi123]

are the Negative solution always going to be the number or ZERO, as in the ZERO will always follow the count of the Negative

[MasterThief1324]

I don't understand what you mean by "Positive" and "Negative" solutions. How did you come to "3 or 1" if there are only 3 sign changes? Where did the 1 come from? Likewise, where did the 0 come from?

[XxMore2LifexX]

@MasterThief1324 you have only 3 positive solutions or 1 because 3-2 = 1. you can't have 2 because you can't have negative solutions. 2-3 = -1

OMG, , THANK U
