Question 744155: Write a quadratic equation in the form ax^2+bx+c=o, having the roots -2 and 5.
I set each root to 0, coming up with (x+2)(x-5). I then foiled them coming up with x^2-3x-10=0. Correct solving method?
Thank You...

Good Job!
You may also realize that there are infinite answers.
x%5E2-3x-10=0 is the simplest one, and simple is beautiful,
but 2x%5E2-6x-20=0 also works.
If you multiply both sides of the equal sign times a number other than 1, you get another equation with the same solutions.
