What code would I use to get the positive root of a quadratic equation?
There are several numerical methods that accomplish this task; try looking into Newton's method.
why not use an if ans to the quadratic eq is positive use it otherwise ignore it?
try 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...
Do 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!
