Question 322200: If you have the solutions: -3 and -2, what would the quadratic equation be? Found 2 solutions by Earlsdon, Edwin McCravy:Answer by Earlsdon(6294) (Show Source):
You can put this solution on YOUR website! If the solution to a quadratic equation are: and then the factors were: and so to find the original quadratic equation, just multiply these two factors: = Simplify this to:
We just do it backwards:
If we had started with a quadratic equation,
solved it and found the solutions were -3 and -2,
we would have ended up with this:
x = -3 and x = -2
Before that, we would have had these two equations:
x + 3 = 0 and x + 2 = 0
Before that, we would have had this product:
(x + 3)(x + 2) = 0
Before that we would have had that FOILed out
before it was factored:
x2 + 5x + 6 = 0
