Best ResponseYou've already chosen the best response.0try it this way 1) function that computes the roots 2) filter out the positive one`s for the 1st part i remember that`s there a problem set that covers this part using newton`s method check that out...

Best ResponseYou've already chosen the best response.0Do you remember the old quadratic equation from grade school?\[x =\frac{ \pm \sqrt{b ^{2}4ac}\ }{2a }\] Because of the plus or minus, two roots will be given. However, it is very important to note that zero, one, or both of the roots could be positive. If I were to write a program given your specifications, I would create a function that plugs an x into the quadratic formula for a given a, b, and c, and then return the positive roots (if any). Let me know if you have any more questions!
