Question

How do you find a quadratic equation with given roots?

Answer 1

You just reverse the process of solving quadratic equations :)

Answer 2

If (x-a)(x-b)=0 gives you a and b as roots, you can just do the reverse

Answer 3

That means if a and b are roots, (x-a)(x-b)=0

Answer 4

C(x-a)(x-b)=0, where C is any constant not equal to 0
