Sorry if this is in the wrong section. I wasn't sure where it went!
If you have an equation:
Which has roots
And you want an equation that has roots
How would you go about this by substitution? Because if i do
Im going to get alpha in terms of beta and u...and if i sub this into the equation im going to still have beta :S...
I know you can do it via sum of roots = -b/a etc but im told in this example to use substitution -,-.
